Paper Abstract

We report an injection-locked single-frequency fiber laser with widely tunable repetition rate. A distributed Bragg reflection (DBR) fiber laser with a central wavelength of 1.063μm and a single frequency continuous-wave (CW) output is used as the master laser. A Fabry–Pérot (F-P) laser diode (LD) with wavelength range of 1.050μm to 1.067μm is used as the slave laser. The single-frequency pulsed laser output is achieved at 1.063μm by controlling pulse, amplitude, temperature of F-P LD and adjusting injection power of DBR fiber laser. The pulse duration can be adjusted between 0.6ns and 40ns. The repetition rate of the laser output can be tuned between 100kHz and 2MHz by tuning the electronic trigger signal. The linewidth is 14MHz when pulse duration is 11ns with repetition rate of 100kHz. The laser with local-oscillator (LO) output shows important value for the applications in the field of coherent LIDAR (Light Detection And Ranging).
