Abstract:
We present a compact green light emitter for laser displays and focus on the pump source for a SHG waveguide in single-pass configuration. The developed pump source has a RW-structure consisting of three sections: a DFB, a spacer and an amplifier section. The optical output power is 305mW for currents of 120mA and 400mA in DFB and amplifier section. The control of the current in the amplifier section allows a modulation of the output power from 5mW to 305mW. Spectral characteristics as well as measured beam divergence are well suited for pumping SHG waveguide crystals. Results on the hybrid 530nm emitter are summarized.
