Embodiment Construction
[0018] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings;
[0019] Such as figure 1 As shown, the U-shaped cavity laser that can be efficiently debugged according to the present invention includes a resonator, a laser debugging device, a laser crystal 9 in the resonator, a pump source 16 symmetrically arranged at both ends of the resonator; 21 and an optical coupling system 18; 19, the pump light emitted by the pump source 16; 21 passes through the center of the laser crystal 9 after being collimated and focused by the optical coupling system 18; 19. The pump source 16; 21 is preferably a laser diode. The pumping source 16; 21 is connected to the optical coupling system 18; 19 through an optical fiber 17; 20.
[0020] The resonant cavity includes a total reflection mirror 14, two reflectors 7; 11, an output mirror 4, a total reflection mirror 14, two reflectors 7; a U-shaped folding cavity formed by 11 and an...
