如果想让LBO在腔内以一定角度放置又要保证相位匹配,单纯改变Φ或者θ可以么?
例如基频光为垂直偏振的1064nm用LBO倍频532nm,如果要LBO在水平面上偏转10°只改变θ
可以么?LBO双轴晶体弄不清楚,我这样想对不对啊?
25℃时
1064.0(o) + 1064.0(o) = 532.0(e)
Walkoff [mrad] = 0.00 0.00 6.94
Phase velocities = c/ 1.605 1.605 1.605
Group velocities = c/ 1.626 1.626 1.639
Group vel. dispersion in 10^5 cm/sec癱m-1=
-0.11 -0.11 -0.55
At theta,phi = 90.0 11.4 deg. |
