High Power Fiber Lasers

High power fiber lasers are created from active optical fibers and semiconductor diodes, a merger between two of the most innovative and advanced laser technologies. Fiber lasers use single emitter semiconductor diodes as the light source to pump the active fibers. The laser beam emitted is contained within optical fibers and delivered through an armored flexible cable. Active fibers, special optical fibers doped with rare earth ions, allow for an extremely bright light from a very small core, thus making possible the production of kilowatt class output with excellent beam quality. IPG uses many proprietary technologies to create the undisputed best beam quality kilowatt class lasers available in the market today.

Fiber Laser Advantages

Our low-order-mode kilowatt class fiber lasers range in power from 500 W to 50 kW, operating in CW or modulated modes up to 20 kHz with wall-plug efficiencies greater than 30%. The dynamic operating range of these devices is available from 10% to full power with no change in beam divergence or beam profile throughout the entire range. This allows a single laser to be utilized for both high and low power applications such as welding, drilling and precision cutting, a previously unheard of capability.

IPG lasers’ divergence specifications are far superior than other lasers and allow the use of long focal length processing lenses for vastly improved depth of field, less damage to optical components and are ideal for remote welding applications. The units can be supplied with fiber lengths to 100 meters, different fiber diameters and variety of multi-port beam switches, beam couplers, termination optics and scanners.Fiber lasers deliver their energy through an integrated flexible optical fiber. Fiber lasers have a monolithic, entirely solid state, fiber-to-fiber design that does not require mirrors or optics to align or adjust. These features make fiber lasers easier to integrate and operate in production, medical and other laser-based systems.

Fiber lasers are typically smaller and lighter in weight than traditional lasers, saving valuable floor space. While conventional lasers can be delicate due to the precise alignment of mirrors, fiber lasers are more rugged and able to perform in variable working environments. These qualities permit fiber laser systems to be transported easily.

The fiber laser is modular, built from multiple laser units, each one generating hundreds of watts of output power. This also allows the laser system to incorporate spare modules and power margins. Due to this modularity the YLS series of high power laser is set to operate below the rated current. Thus, in the unlikely event thata module fails the laser will automatically increase the power to the rated output leaving the laser with no output power loss and no halted production. An error message will then alert the user of the specific issue that requires service.

Laser Classifications

Each classification of high power fiber laser serves a targeted application demographic. The most versatile and customizable option within the product line is the YLS series fiber laser. Developed as a complete system, this design features the widest range of fiber diameters, as well as the option to terminate to up to 6 ports from one power source. Housed in a NEMA 12, air conditioned and sealed cabinet, these systems are designed to operate in industrial manufacturing environments. They have garnered wide acceptance in the very demanding automotive, aerospace and oil and gas industries, many requiring multiple shifts operating.

Replicating the versatility of the YLS series,the YLS-TR comes bundled with a compatible chiller or heat exchanger. Additionally, the
TR Series has the added feature of dual cooling lines: one directly to the laser, the other cycling warmer water to the external optics, thus reducing condensation which is especially advantageous in warmer climates. With the most compact design, the YLR laser is offered as a cost-effective, adaptable solution for a clean room system or for integrationinto a production line. Directly terminated to
a QBH-type connector (HLC-8) with numerous feed fiber lengths and diameters available, the rack mount configuration is ideal for a multitude of applications from cutting, welding and drilling to medical device manufacturing.

Pulsed Fiber Lasers

The YLP Series are maintenance-free MOPFA and Q-switched pulsed Ytterbium fiber lasers designed for OEM applications. Collimated, isolated and then typically focused to a spot size of a few microns or less, the near diffraction-limited beam can mark, drill or machine a variety of materials. Similar to the standard YLP series, the YLP- RA has a remote amplifier in place of the standard output which allows for an even higher peak power and a shorter pulse duration. The amplifier features a thermo- conductive bottom surface with the option for a heat sink with one fan for even more adaptability.

The YLP-M series are master oscillator power amplifiers, or MOPA lasers, that feature a selectable output. These lasers are constructed with a seed diode allowing for multiple pulse durations. There are two different builds of the MOPA laser; one is the OEM module which is available in either 10 or 20 Watt output power, the other is an 18 Watt MOPA in a 3U industrial chassis which already included the full user-friendly interface and power supply.The YLP-HP series feature the highest pulse energy and output power of the YLP units. The increased power levels allow you to work more efficiently and use thicker materials.

Additionally, due to the low pulse duration the YLP-HP is proficient in processing ablating applications as well due to the minimal damage to the substrate material. Like IPG’s other industrial pulsed lasers, this laser is based upon IPG’s ultra-reliable pumping technology and comes with a heavy duty optical isolator that improves output pulse stability and eliminates back reflection.

Optical Coupling, Switching & Sharing

Maximizing Your Fiber Laser’s Capabilities he ability to couple light from one fiber to another greatly expands upon IPG’s fiber laser functionality. A single laser can be used as a power source for multiple work cells thus reducingthe total cost of capital equipment. A multi-port unit offers the option of attaching variedprocess fibers where each work cell could be operating on a different application; for instance one port could weld with a 300 μm diameter fiber in one cell while another port operates witha 100 μm fiber thus providing power to two workstations from a single laser. In addition togreater functionality, optical coupling also provides for ease of replacement of the process fiber, be it for altering the parameters for an application or in an instance of accidental damage to the fiber. If damage does occur, the main power source stays intact and operational for other channels, thus providing greater protection to the power source.

Available options include either a single port coupler, a multi port beam switch offered in either 2, 3, 4 or 6 channels, a beam shutter (also known as a 1×1 switch, used for increased process speeds) or a 2 port beam sharing function with the additional option of 100% full power in one port. Each component is available in a multitude of configurations depending on the chosen power source, series and the size of the

Laser Control Software Program

Interface Options and Abilities IPG fiber lasers feature the most up to date control functions requested by the industry. Interfaces such as Profibus, DeviceNet, Industrial Ethernet or simple digital I/O make integration with complex equipment straightforward and easy to use. All laser parameters and available peripherals such as a multi-channel beam switch, chiller, guide laser, power supply, etc. are constantly monitored and controlled by an internal computer and can be remotely accessed at any time. A convenient graphical user interface can be installed on any customer PC. In addition, IPG’s fiber lasers have conventional interfaces such as analog control and direct modulation. Response time to these signals is less than 50 microseconds which is crucial for applications with on-the-fly adjustments. Moreover, the laser can store up to 50 different programs with 100 commands each which can be called out with the simple push of a button or via external digital signal.
