近几年来，随着二极管激光器（LD）的迅速发展，全固态被动调Q激光器件由于结构简单、操作方便、不需要外围设备，因而在科研、军事和工业等领域中有广泛的应用．其中，用掺四价铬的钇铝石榴石晶体（Cr4+：YAG）作被动调Q元件，在连续波或准连续的Nd：YAG中，已获得皮秒脉宽、
In recent years, with the rapid development of diode laser (LD), all-solid-state passive Q-switched laser devices are widely used in the fields of research, military and industry due to their simple structure, convenient operation and no peripheral equipment. Among them, the passive Q-switching element is made of yttrium aluminum garnet crystal doped with tetravalent chromium (Cr4 +: YAG). In the continuous wave or quasi-continuous Nd: YAG, the picosecond pulse width has been obtained,
