In order to study the output characteristics of diode-end-pumped Nd:YAP laser operating at 1341.4nm,the thermal focal lengths of end-pumped Nd:YAP laser were calculated and measured,and the output results of lasers with plane-plane and plano-concave resonators were compared respectively.

为了研究Nd：YAP晶体在LD端面抽运中的1341.4nm激光输出特性，采用理论计算和实验测量了实验系统的热焦距，对比了平平腔和平凹腔激光输出结果。

He to ld me plump that he would not give in.

他直截了当告诉我，他决不让步。

Plate and λ/2 plate were placed inside the Nd∶YVO4KTP green laser cavity with angle 90°between their fast axis.The composite plate composed of HWP,QWP and KTP has the function of QWP.The composite plate with Nd∶YVO4 can effectively suppress the coupling of polarized modes,and multi-longitudinal-mode lownoise green laser was obtained.Since the composite plate counteracted the phase shift induced by temperature sensitivity of quartz plate,the green laser operated with lownoise reliability in different output power and different operation temperature.The threelongitudinalmode, the noise of less than 0.5% and output power stability of less then 1% for 12 hour are obtained in the green laser.

介绍了一种LD泵浦腔内倍频全固体Nd∶YVO4KTP多纵模、低噪音、高功率稳定绿激光器在Nd∶YVO4KTP绿激光器组成的谐振腔内放置厚度约相等的石英晶体λ2波片和λ4波片，使两波片快轴夹角互呈90°，HWP、QWP与KTP构成复合波片，其作用相当于QWP，此复合波法与各相异性Nd∶YVO4共同作用有效抑制了腔内偏振模耦合，获得多纵模低噪音绿光输出此复合波片相互作用由于抵消了石英晶体波片温度敏感引起的相位延迟量漂移，所以此激光器在不同功率、不同工作温度下，均能稳定可靠地运转于低噪音状态实验结果为，绿光输出纵模数为3个，噪音小于0.5%，12 h功率稳定性优小于1

In recent years, the fiber grating external cavity semiconductor laser regarded as one of the candidate light sources of DWDM systems, has received considerable attention. Usually, it is thought that the lasing wavelength of a FGESL is locked at the Bragg reflection wavelength of fiber grating.

由于FGESL的激射波长主要由光纤光栅的布拉格波长确定，因此选择具有合适布拉格波长的FG就能使FGESL的激射波长处于预置波长处；同时，由于FG的布拉格波长受温度变化的影响相对较小(～0.01nm／℃)，因此FGESL与DFB-LD相比具有更高的温度稳定性。

He to ld himself that he did not love Roberta, that it was Sondra whom he wished to marry.

他提醒自己他并不爱罗伯塔，桑德拉才是他想娶的姑娘。

The next thing that we now need to do is to ensure that the user _id is unique by placing the p roper index on the user_id fie ld.

下一件我们现在需要做的事情是通过在 us er_id 域放置恰当的索引确保 user_id 是唯一的。
