IPG Photonics offers ELS Series of a high power CW erbium fiber lasers with a central wavelength 1567 nm and output power in kW range. Available for R&D, materials processing and low loss power transmission applications, ELS systems open up new exciting areas of applications development. In the 1.5 micron region, IPG Photonics brings you the broad range of devices, from lasers to amplifiers and from tunable lasers to broadband sources, in a variety of powers and configurations. Our fiber devices provide the best in diode-pumped solid state reliability and performance. With thousands of units in the field, you can be assured that IPG products are proven and reliable for your demanding application.
| Output Power up to 4 kW | Beam Parameter Product < 5.5 |
| Central Wavelength 1567 nm | Power Stability < 2% |
“Eye-Safe” operation generally means that eye damage threshold is many orders of magnitude higher than for 1 μm lasers. Nevertheless IPG recommends that appropriate eyewear be worn and laser safety procedures be followed.
