Partially end-pumped slab laser is an innovative solid state laser, namely InnoSlab. Combining the hybrid resonator with partially end-pumping, the output power can be scaled with high beam quality. In this paper, the output intensity distributions are simulated by coordinate transformation fast Fourier transform (FFT) algorithm, comparing the thermal lens influence. As the simulated curves showed, the output mode is still good when the thermal lens effect is strong, indicating the good thermal stability of InnoSlab laser. Such a new kind of laser can be designed and optimized on the base of this simulation.

InnoSlab Laser用混合腔的输出光束质量问题从热透镜效应和腔镜的不对准两个方面的影响进行理论分析,并从远场光强分布、远场发散角、光腰半径、光束质量因子M2值和桶中功率曲线等几个角度进行了讨论,特别是离轴非稳腔方向上腔镜倾斜对光束质量的影响,利用M2值和PIB曲线两个参数共同评价非稳腔的光束质量,对目前并无统一标准的非稳腔光束质量评价问题提供了有意义的参考.

部分端面抽运的板条激光器是一种新型固体激光器.配合混合腔可以实现在大功率下保持高光束质量的激光振荡输出。谐振腔的腔镜倾斜是影响激光器输出特性的重要因素,快速傅里叶方法是一种快捷有效的计算方法,利用此方法模拟了腔镜倾斜对近场相位分布和远场光强分布的影响,并分析了光束质量的变化。理论分析表明,腔镜的小角度倾斜对近场相位影响较大,但对远场光强空间分布影响不大;随着倾斜角度不断增大,远场发散角和光束腰宽度也增大,光束质量虽然存在恶化的趋势,但光束质量因子肝值仍然较小,离轴非稳腔仍能保持高光束质量的输出。
