1018nm Narrow Linewidth DFB Chip On Carrier 150mW

Description

The 1018-1120nm DFB Series of high-performance edge-emitting laser diodes are based on SLT’s advanced monolithic single-frequency Gallium Arsenide (GaAs) based laser technology. It provides a single spatial mode beam and has passivated facets for reliability. The 1018nm Series DFB devices are used in frequency doubling applications as a low-noise optical pump source
