Embodiment 1
[0042] Such as figure 1 As shown, Embodiment 1 of the present disclosure provides a wavelength tunable nonlinear mirror mode-locked laser, including a pumping light source 1. The pumping light source 1 is focused after being passed through a collimating and focusing system 2, and then enters an optical resonant cavity after focusing. The optical resonant A laser crystal 7, a birefringence filter 9 and a nonlinear crystal 8 are sequentially arranged in the cavity.
[0043] The pumping light source 1 is a continuous or quasi-continuous light source, preferably a 976nm diode laser.
[0044]The beam resonant cavity is a Z-type resonant cavity including an input mirror, two reflectors and an output mirror, and the two reflectors are respectively a first reflector 4 and a second reflector 5, and the first reflector 4 and the second reflector Reflectors 5 are arranged at the corners of the Z-shaped resonant cavity respectively, and the first reflector 4 is used to receive the input ...
Embodiment 2
[0064] Such as Figure 6 As shown, Embodiment 2 of the present disclosure provides a working method of a wavelength tunable nonlinear mirror mode-locked laser;
[0065] A working method of a wavelength tunable nonlinear mirror mode-locked laser, using the wavelength tunable nonlinear mirror mode-locked laser described in Embodiment 1 of the present disclosure, the steps are as follows:
[0066] The pump light source sends a collimated beam to the optical resonant cavity through a collimating focusing system;
[0067] The laser first works in the continuous wave state, and the birefringent nonlinear crystal changes the angle or the optical superlattice changes the period or temperature to match the phase of the frequency doubling process and realize the mode-locked laser output;
[0068] The laser output wavelength is changed by changing the angle of the birefringence filter.
[0069] The input mirror has high transmittance to 976nm light, high reflectivity to 1020nm-1080nm l...
