| Abstract: | Aiming at the special technique requests of directed infrared countermeasure systems for mid-wave infrared (MWIR) lasers in laser wavelength, power,divergence,repetition frequency and modulation pattern, the technique characteristics and present developing situation of the optically pumped semiconductor disk laser,the quantum cascade laser, the optical-parametric-oscillator-based solid-state laser and fiber laser were analyzed .The characteristics and new developments of the birefringent phase matching and the quasi-phase matching were also summarized. A technique project of MWIR lasers was proposed by using a solid-state laser or a fiber laser with the wavelength of 1 064 nm and high power good beam quality to pump an optical parametric oscillator based on the crystal of periodically poled lithium niobate with MgO-doping(PPMgLN).The converting efficiency above 16% on wavelength could be obtained. |
