Fully integrated HB-diode system delivers 75 W of power at either 808 nm from 200 µm core 0.22 numerical aperture fiber, or 976 nm from 400 µm core 0.22 numerical aperture fiber. It operates from 110/220 Vac, and enables user control of diode output through either front panel keypad or electronic interface, including analog, TTL, RS232/485. For range of applications, laser system also has air cooling, rack mounting option, and coaxial, visible wavelength aiming beam.
