Beam Mode Quality :
Depending on the application requirements, the CW lasers in 100 W – 1.5 kW power range are
oﬀered with either single-mode or multi-mode beam quality. Due to absence of thermal lensing refractive index gradients in the laser cavity, fiber lasers maintain beam mode quality and divergence when the output power is adjusted. This is not the case with DPSS bulk lasers which are typically optimized to run at nominal power level.
The CW fiber lasers in the 100 W – 1.5 kW power range are typically oﬀered with random polarization; linear polarization is an option. We also oﬀer linearly polarized ytterbium CW fiber amplifiers up to 1 kW. Please contact your IPG Photonics representative if linear polarization is required.
Direct Modulation :
Direct power modulation in the kHz range is a standard feature.
Power Stability :
Typical power stability is <1% over 4 hours under stable environmental conditions.
YLR rack unit lasers are air cooled up to 500 W and water cooled upto 1500 W output power.
The lasers are packaged as either OEM modules or as 19” rack mountable units. OEM modules require a DC power source, rack mounted units require single phase 50-60 Hz power source. The rack mounted units have front panel control of laser power and LCD display. OEM modules are controlled through RS-232.
Multimode YLR :
100 – 1500 W lasers equipped with a standard 50μm feeding fiber to HLC-8 connector. Additional options include 100 or 200 μm Φ to HLC-8 connector or 50,100 or 200 µm to an aﬃxed collimator.
Singlemode YLR :
100 -1500 W lasers are equipped with a 5mm beam Φ aﬃxed collimator for powers up to 400 W; 500 – 1500 W lasers terminate to an HLC-8 connector.
