Output Characteristics of Littrow-Type Grating External Cavity Semiconductor Lasers
The theory of grating external cavity semiconductor lasers is discussed, and the influences of different factors on the output power and linewidth reduction of the Littrow-type external cavity semiconductor lasers are numerically simulated. The Littrow-type grating external cavity semiconductor laser is set up, and single longitudinal mode and highly-equality laser output is realized. The continuous output power is achieved with 180 mW at working current of 400 mA and the spectrum linewidth is less than 1 MHz.
