摘要
报道了利用激光二极管(LD)端面抽运Nd∶YVO4+KTP胶合晶体得到波长分别为532,537和542 nm激光输出的实验研究。通过调节晶体的角度,发现在KTP晶体中1064 nm倍频,1064与1084 nm和频,以及1084 nm倍频3个非线性频率转换过程同时存在。从非线性频率转换效率对基频光振荡的影响角度出发,讨论了1064 nm和1084 nm双波长振荡的条件,分析了激光器在不同抽运功率条件下3个输出波长功率变化的原因。
A laser diode（LD） end-pumped optical-contact composites Nd∶YVO4＋KTP three-wavelength laser is reported.The output laser wavelengths are 532,537 and 542 nm respectively.By adjusting the angle of the crystal,1064 nm doubling frequency,1064 and 1084 nm sum-frequency and 1084 nm doubling frequency coexist in KTP crystal.From the impact of nonlinear conversion efficiency on fundamental oscillation,the condition of 1064 nm and 1084 nm dual-wavelength oscillation was discussed and the reasons of three wavelengths power changing with pump power were studied.
