SAN JOSE, Calif., June 16, 2013 — Oclaro Inc.’s new distributed feedback (DFB) 1060-nm laser diode module, featuring an on-chip distributed feedback grating, is designed for the seeding of subnanosecond fiber and solid-state lasers.

Capable of peak powers up to 800 mW for a pulse width as short as 150 ps and a spectral line width below 100 pm, the laser enhances pulse amplification and frequency conversions to green and UV wavelengths. These short pulses enhance the quality of materials processing and mitigate the stimulated Brillouin scattering problem with pulse fiber lasers that occurs above 10 ns. In CW mode, the module delivers 200 mW of optical power with a 3-dB line width of 150 kHz and 50-dB side mode suppression ratio.

The module features a standard telecom butterfly-type package that includes a thermistor and back-facet monitor photodiode. Reliability of the DFB chip has been demonstrated with more than 8000 h of multicell life-testing at accelerated operating conditions with zero failures.
