Product description: 

 High-precision automatic power control and automatic temperature control, high power stability, continuous light work. 
 Spectrum of semiconductor lasers can be a single longitudinal mode, can also be a multi-longitudinal mode. Single longitudinal mode simply means that the spectrum of distributed feedback (DFB) semiconductor laser is grating on the active region of semiconductor lasers instead of reflecting surface reflection grating only reflect a certain wavelength of light, so select the multiple spectrum inherent wavelength with grating light shock to output a single longitudinal mode laser.
