All-solid-state Tone Q671nm Laser Pumped Tunable Cr (3 +): Lisaf Laser

Tunable lasers especially the solid state tunable lasers ,which maintain the merits of high stability,high efficiency,compactness and long lifetime , has shown their versatile abilities in optical-fiber commimication> information storage photoelectric detecting^ isotope analyzing. This dissertation present theoretical and experimental research on tunable Cr?~:LiSAF laser which was end-pumped by a accousto-optical actively Q-switched Nd:YV04\ LBO intra-cavity frequency doubling 671nm laser. The contents can be described as follows:1. Review the history of tunable lasers, made comparation among solid tunable lasers .2. A theoretical study of input and output properties of four-level solid laser was performed according to the velocity equation ,and the important role of the overlap integral J, was noticed and made a fully usage in optimizing the end-pumping solid state laser parameters such as: rod length > pump position pumping and oscillating beam waist size .3. The thermal-mechanical and lasering properties of Cr*:LiSAF crystal were carefully studied .especially the up-conversion and the ESA effect. All of these were given fully considered when design the three-mirror folded cavity tunable LiSAF laser which was pumped by a accousto-optical active Q-switched Nd:YVO4\ LBO intra-cavity frequency doubling 671nm laser.4. At last a theoretically design of the optimizing Kerr effect self-mode locking Cr~:LiSAF laser was performed for further research.
