摘　　要：在腔内不添加任何调谐元器件,并且不改变输出耦合率的情况下,分析能级寿命和受激辐射截面,调控泵浦脉冲模式,实现同一台激光器中多种波长模式的输出。典型输出模式包括:2 699 nm激光(1.06 mJ)和2 803 nm激光(1.25 mJ)的单波长输出,2 699 nm(1.06 mJ)和2 803 nm(0.86 mJ)双波长激光的时间分离分频输出,2 699 nm(1.06 mJ)和2 830 nm(1.35 mJ)双波长激光的时间分离分频输出。本文研究有望成为测量有机物浓度的差分吸收雷达的光源,使单一探测器实现差分测量,同时大幅度简化差分吸收雷达的检测系统,降低成本。This work achieves a variety of wavelength output modes in the same laser by analyzing the energy level lifetime and thestimulated emission cross section.The laser realizes the result by the regulation of the pump pulse mode without any tuning components in the cavity and does not change the output coupling transmittance.The laser modes include:1.06 mJ single-wavelength 2699 nm laser mode,1.25 mJ singlewavelength 2803 nm laser mode,alternate sequence pulse mode with dual-wavelength of 1.06 mJ 2699 nm and 0.86 mJ 2803 nm,alternate sequence pulse mode withdual wavelength of 1.06 mJ 2699 nm laser and1.35 mJ 2830 nm.The research in this paper is expected to be the laser source of the differential absorption radar for measuring the concentration of organic matter,enabling a single detector to achieve differential measurement,while greatly simplifying the detection system of differential absorption radar and reducing costs.
