摘　　要：用加热法和压电陶瓷ＰＺＴ调腔的方法，实现二极管激光泵浦的单频运转１０６４ｎｍ２％Ｎｄ：ＹＶＯ４激光器调谐。调谐范围４７．４ＧＨｚ，增益峰漂移引起的激光频率温度系数／Ｔ＝—１．０４ＧＨｚ／℃，压电陶瓷调谐系数１５０ＭＨｚ／Ｖ。研究了加热影响器件性能的情况。The operatins characteristics of a 1064 urn sinsle-frequency tunable diodepumped Nd-doped (2%) YVO4 laser are described. Tuning is accomplished by means of a piezo-electric transducer (PZT) mounted on the output coupler for cavity length control and the laser crystal heatins. The laser has been tuned over a range of 47 GHz without mode hopping. The tuning coefficientS up to 150 MHz/V for PZT and temperature coefficientS -1. 04 GHz/℃ for the gain center frequency are demostrated.
