By adjusting the pitch angle of the output mirror (5) from -5° to +5°, the Fresnel number of the resonant cavity is changed to further realize the laser output of different order modes.
实施例3：双波长输出的角动量可调谐全固态激光器Example 3: Angular momentum tunable all-solid-state laser with dual-wavelength output
如实施例1所述，所不同的是：省掉输入镜（3），固体激光介质（4）是Nd:Lu2O3晶体，在固体激光介质（4）的入射面上镀以对泵浦光808nm透过率≥90%、对振荡光1077nm和1080nm光反射率≥99%的介质膜，用以取代输入镜（3）的作用；另一端不镀膜。结构如图3所示。As described in Example 1, the difference is that the input mirror (3) is omitted, and the solid laser medium (4) is Nd:Lu 2 O 3 crystal, which is plated on the incident surface of the solid laser medium (4) to support the pump Dielectric film with transmittance ≥ 90% at 808nm and reflectivity ≥ 99% for oscillating light at 1077nm and 1080nm is used to replace the input mirror (3); the other end is not coated. The structure is shown in Figure 3.
