Abstract

We report an all-solid-state QCW (quasi-continuous-wave) tunable Ti:sapphire laser system from 697nm to 942nm, which was pumped by an intra-cavity frequency doubling Nd:YAG laser at 532nm. Under the pump power of 18W at 532nm with the repetition rate of 3.9kHz, the average output power of 3.5W at 795nm with an optical conversion efficiency of 20% was yielded. Through extra-cavity frequency doubling with the nonlinear crystal LBO (LiB₃OWe report an all-solid-state QCW (quasi-continuous-wave) tunable Ti:sapphire laser system from 697nm to 942nm, which was pumped by an intra-cavity frequency doubling Nd:YAG laser at 532nm. Under the pump power of 18W at 532nm with the repetition rate of 3.9kHz, the average output power of 3.5W at 795nm with an optical conversion efficiency of 20% was yielded. Through extra-cavity frequency doubling with the nonlinear crystal LBO (LiB₃O₅), cut for critical type I phase matching (θ=90°, φ=33.2°) at room temperature, tunable second-harmonic generation (SHG) from 350nm to 465nm was achieved. Through the design of the scan and control system, the whole laser system can be used to expose the sensitive material under the controlling of computer.
