| 摘 要： | 以激光二极管阵列抽运Nd：YAG内腔倍频激光器作为抽运源，实现了全固态准连续钛宝石激光器的高功率、高效率运转。当532nm的抽运光为24W时，得到了4．7W输出功率及19．6％的高转换效率。为了获得钛宝石激光器理想的宽带输出，分别使用了两组膜片。第一组是750～850nm，第二组是850～950nm，每组膜片都有三种透过率，分别为5％，10％，15％。由于钛宝石荧光谱线的中心波长在795nm附近，使用第一组膜片在透过率为10％的情况下获得了最大4．7W的输出功率。使用第二组膜片也获得了3W左右的输出功率，为将要进行的宽带调谐提供了必要的前提。

| Abstract: | Using frequency-doubled Nd : YAG laser pumped by laser-diode-array as pump source, a high output power, high conversion efficiency, all-solid-state, quasi-continuous-wave Ti:sapphire laser system is achieved. The maximum of the Ti:sapphire laser output power of 4. 7 W and the conversion efficiency of 19. 6% are obtained at 532-nm pump powr of 24 W. To ensure the ideal broadband output of Ti:sapphire laser, two sets of Ti:sapphire resonator mirrors were used, respectively. One is from 750 to 850 nm, the other is from 850 to 950 nm. And the transmissivity is 5%, 10%, 15% respectively for two sets. Because the centric wavelength of the resonator laser is nearly 795 nm, the maximum of the Ti:sapphire laser output power is 4. 7 W with the first set of mirror and the transmissivity of the output mirror is 10%. The second set of mirror can generate the output power of 3 W, which is high enough to achieve broadband tuning for the future. |
