Particularly, cr4 + - doped crystals as passive q - switch ( saturable absorber ) have got extensive attention, such as cr4 + : yag ， cr4 + : gsgg ， cr4 + : mg2sio4 and cr4 + : yso, which have the advantages of wild absorption band, good saturable absorption, long restored time, good photo - chemical stability, no fading, good thermal conductivity and high damage threshold
特別是近年來，摻cr4 +離子的各種晶體如cr4 + : yag ， cr4 + : gsgg ， cr4 + : mg2sio4和cr4 + : yso等作為被動調q開關受到了廣泛的關注。它們具有很寬的吸收帶和良好的飽和吸收性質，恢復時間較長，光化學性質穩定，無退化現象，熱導性好，損傷閾值高。 -
In low laser intensity, cr4 + : yag can be used as slow saturable absorber. the nearer is the initial transparence to the max initial transparence, the bigger is the loss modulation
在光強不太大的情況下， cr ~ （ 4 + ） yag可作為慢飽和吸收體，其初始透過率越靠近最大初始透過率，損耗調制越大。 -
Some researches about frequency doubling are made, and two methods to improve intensity of second frequency generation are given. we realized q - switched 532 nm laser, by using nd : gdvo4 as laser crystal, using cr4 + : yag as saturable absorber, using ktp as intra - cavity frequency doubling crystal. average power of 109mw, repetition of 40khz, pulse width of 30ns, pulse energy of 2. 6uj, peak power of 91w are obtained
4 .對倍頻理論進行研究和分析:討論兩種提高二次諧波功率密度的方一法;實驗匕在國內首次實現ld端面泵浦nd : gdvo4 / ktp ，用cr4 + : yag作為可飽和吸收片的綠光激光器，腔內倍頻得到了平均功率為109mw 、重復頻率為40khz 、脈寬為3ons 、單脈沖能量為2 . 6閃、峰值功率為glw的調q綠光輸出。
