强泵浦固体激光器时，有源介质的热透镜会产生严重的球差。基模轮廓由于像差而恶化。用Fox{Li}微分迭代算法计算了有像差的谐振腔的自洽模。计算结果表明，像差引起的基模光束质量恶化与谐振腔的设计密切相关。在稳定性的中间，谐振腔处{∞处的a ∞对像差系数的容差约为30 Ω，其中Ω是激光束的波长。但是对于动态稳定的谐振腔，如果采用不适当的设计标准，2“的球差将产生超过40%的衍射损耗。对双Nd：YAG棒双折射补偿激光谐振腔进行了实验研究。实验数据与模拟结果吻合较好。
Spherical aberrations of the thermal lens of the active media are severe when solid state lasers are strongly pumped. The fundamental mode proflle deteriorates due to the aberrations. Self-consistent modes of a resonator with aberrations are calculated by using the Fox{Li difiraction iterative algorithm. Calculation results show that the aberration induced fundamental mode beam quality deterioration depends greatly on the resonator design. The tolerance of a ∞at{∞at resonator to the aberration coe‐cient is about 30‚ in the middle of stability, where ‚ is the wavelength of laser beam. But for a dynamically stable resonator, 2‚ of spherical aberration will create difiraction loss of more than 40%, if inappropriate design criteria are used. A birefringence compensated laser resonator with two Nd:YAG rods is experimentally studied. The experimental data are in quite good agreement with simulation results.
