摘要: 设计并研究了Nd:YVO4自锁模皮秒激光器,探究了激光器的最佳锁模条件。观察并分析了自锁模皮秒激光器准周期锁模、倍周期锁模状态,研究并测量了结构紧凑的直腔自锁模激光器的输出特性。谐振腔为凹平直腔,Nd:YVO4晶体作为激光增益介质和克尔介质,在未加其他锁模元件的情况下,实现了1 064 nm高效率连续锁模脉冲激光输出。晶体距输入镜16 mm、腔长为90 mm时,对1 064 nm透过率分别为10%、20%、30%和50%的四种输出镜下激光器的输出特性进行了对比分析。对激光器进行优化设计,输出镜透过率为10%,泵浦功率为8 W时,激光器输出功率为2.76 W,斜效率高达43.2%,锁模脉冲重复频率为1.43 GHz,激光器实现了高效、稳定的连续锁模。

Abstract: The Nd:YVO4 self-mode-locked picosecond laser was designed and studied, and also the best conditions of the mode-locked lasers were explored. The period-doubling self-mode-locked pulses and the quasi-periodic self-mode-locked pulses in the picosecond laser were observed and analyzed, and the output characteristics of the self-mode-locked laser with straight cavity in compact structure was studied and measured. The resonant cavity was concave flat chamber, under the condition of no other clamping device, the Nd:YVO4 crystal as a laser gain medium and Kerr medium, and the high efficiency continuous mode-locked 1 064 nm laser pulses were outputted. The Nd:YVO4 laser crystal is 16 mm from the input mirror, and the cavity length is 90 mm. The four kinds transmittance in 1 064 nm of output mirror are 10%, 20%, 30% and 50%, respectively, meanwhile the output characteristics of the laser were analyzed in comparison with different output mirrors. By optimizing the design, when the transmittance in 1 064 nm of output mirror is 10%, the output power of the laser is 2.76 W at 8 W incident pump power, and the slope efficiency is up to 43.2%, the repetition rate of mode-locked laser is 1.43 GHz, the laser achieves a high powered and stable continuous wavelength mode-locked.
