摘　　要：通过谐振腔腔结构理论研究了在端面泵浦固体激光器中 ,等效热反射镜曲率半径变化时 ,振荡光半径的变化速率 理论和实验都表明 ,通过调整谐振腔的参量 ,使得该变化速率接近零 ,可以有效地抑制热效应导致的激光功率不稳定性 。A method to design laser cavity with low thermal noises is reported. Based on the traditional cavity theory, the laser radius is taken as the function of focus length of the thermal lens, and its derivative is studied. By experiments on a diode end-pumped solid-state laser it is showed that when the derivative equals zero, the laser′s thermal noises is significantly reduced.
