The noncollinear SHG method has been used to measure the pulse width of passively mode-locked Nd: YAG laser. The nonlinear ADP crystal is oriented in such a way that phase matched SHG is produced only when both incident beams are present as ordinary rays. The angle between the two beams is 25°50′. Phase-matched SHG as an extra-ordinary occurs at an angle bisecting the two beams. The correlation width obtained with passively mode-locked Nd: YAG corresponds to a pulse width of 24 ps.

用非共线自相关SHG方法测量了Nd:YAG被动锁模激光器的脉冲宽度。非线性晶体ADP的取向是使仅在两束光都存在时才有位相匹配的SHG。两束寻常光之间的夹角在晶体中是20°50′。SHG出现在它们的角分线方向上;倍频输出是非寻常光。所测得的自相关函数的宽度对应着Nd:YAG被动锁模激光器的脉冲宽度为24ps。

In this paper the effect of junction capacitance, spontaneous recombination, DC-bias and injected pulse current on time delay' of turn-on of injection lasers modulated by pulse currents is analysed comprehensively. Kinetic equations considering those factors are developed. A variety of possible cases for are discussed, and results for some typical parameters are given. The calculated results are found to coincide with the measured values. When the junction capacitance is not very small (>20 pF), it is an important factor for the time delay just like spontaneous recombination. The reduction of the time delay by DC bias is not linear, becoming small gradually from zero-bias to DC-bias at threshold. Thus we can obtain the best modulation by DC-bias below threshold.
