Optically pumped surface-emitting DFB GaInAsP/InP lasers with circular grating
The lasing action in surface-emitting DFB lasers with circular grating (SE-CG DFB) is reported for the first time. 1.283 mu m laser oscillation is demonstrated by optical pumping. The threshold pumping power density is estimated to be 16.2 kW/cm2. The pulsed output power is more than 25 mW.
16.2 kW per sq cm is a lot of power. It would heat up anything including the atmosphere.
