Definition
The 1030nm DFB (Distributed Feedback) laser is a pulsed semiconductor laser with a peak wavelength of 1030 nanometers (nm) and employs a distributed feedback structure. Its operating principle is based on a distributed feedback mechanism, which allows for the precise control of grating parameters and pulse injection conditions to achieve high peak power and precisely controlled wavelength laser pulses.
