Long wavelength multiwatt 1310 and 1550 nm grating-outcoupled surface-emitting semiconductor lasers

Photodigm is developing long wavelength multiwatt grating outcoupled surface emitting (GSE) semiconductor lasers with continuous-wave (CW) output powers exceeding 1 W at 1310-nm and 0.4 W at 1550-nm wavelengths. These GSE lasers have full-width at half-maximum (FWHM) spectral bandwidth of less than 0.2 nm and a beam divergence of 0.5° x 3.2°(FWHM).
