论述自锁模钛宝石激光器谐振腔的像差补偿问题，分析了“X”型与“Z”型谐振腔彗差的大小，由此对这两种腔作出比较，指出“X”型腔的优点。在这样设计的激光器上，获得了19fs激光脉冲输出，功率为320mw，中心波长为784um，全半宽度为42um。
The problem of aberration compensation in the self-locking Ti-sapphire laser resonator is discussed. The size of the coma of the “X” and “Z” resonators is analyzed, and the comparison between these two kinds of cavities is made. advantage. In this design of the laser, obtained 19fs laser pulse output, power 320mw, the center wavelength of 784um, the full width at half maximum 42um.
