摘要:
采用671 nm红光泵浦Cr∶LiSAF激光晶体,实现中心波长为849 nm,调谐范围为820~890 nm,脉冲宽度为100 ns,重复频率为11 kHz的激光输出.该系统阈值功率为24 mW,激光输出最大平均功率可达60 mW,此时泵浦功率为521 mW.使用电荷耦合器(charge coupled devices, CCD)探测器及图像采集系统,观察并记录了输出光光斑.通过调节晶体及输出镜使光斑的形状和个数发生变化,针对输出光斑为1~3个点的情况进行详细研究,分析不同情况下的输出特性.实验结果表明,激光输出功率和光斑之间的最大距离会随泵浦功率的增加而递增.
Abstract:
With the Cr∶LiSAF pumped by using 671 nm red light,achieved the output beam of wavelength 850 nm,tunable from 820 nm to 890 nm,repetition rate of 11 KHz and pulse width of 100 ns.The power of the output beam reached 60 mW under the 521 mW pump power.The CCD camera was used to observe and record the variation of output beam spots with readjusting the output couplers angle.Under different conditions,the characteristic of output laser will be different.In this work,1~3 laser spots were observed and discussed in detail.It is demonstrated in the experiment that both the output power and the maximum distance between these spots increased with the augment of pump power.
