Research Of Dual-Channel All-Solid-Compound Cavity State Laser Of 589nm

Yellow lasers have became an hot topic recent years. It is used extensively in interference rainbow holograph, fine laser spectrum, differential absorption lidar, nonlinear frequency conversion, laser medicine and so on. It is compact and miniaturization, which can provide high output power and the bands which is more important. The all solid state lasers which can emit 589nm wavelengths simultaneously have great potential application in high brightness laser multicolor display, laser multicolor print and other equipments and entertainments by frequency transform.The paper mainly studied Nd:YAG crystal, and made theoretic and experimental research about the four-lever system. The rate equation theory for the Nd:YAG laser is put forward. The experiment of a diode-side-pumped Nd:YAG all-solid-state laser which can realize the simultaneous operation is reported. After designed and calculate with computer, we made the experimental installation with the result. Finaly a 589nm radiation were achieved.
