摘要
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 aberration of a resonator for self-mode-locked Ti:sapphire laser is studied. The influence of the coma to the X-shape and Z-shaPe cavity is analyzed. The advantage of the X-shape cavity is indicated in comperison with Z-shape cavity. As short as 19 fs pulses have been obtained from this laser with average power of 320 mW and bandwidth of 42 nm at center wavelength of 784 nm.
