摘要:
An all-solid-state quasi-continuous-wave (QCW) tunable Ti:sapphire laser system from 697 nm to 942 nm by using single output mirror is reported, which was pumped by an intra-cavity frequency doubling Nd:YAG laser at 532 nm. Under the pump power of 18W at 532 nm with the repetition rate of 3.9 kHz, the average output power of 3.5 W at 795 nm with an optical conversion efficiency of 20% was yielded. Through extra-cavity frequency doubling with the nonlinear crystal LBO (LiB3O5, 3 mm6 mm20 mm), cut for critical type I phase matching (Θ=90, Φ=33.2) at room temperature, tunable second-harmonic generation (SHG) from 350 nm to 465 nm was achieved. The average output power at 400 nm was 540 mW. Through the design of laser focus system , the scan and control system, the whole laser can be used to expose the CTP material. In this way, the capability of the CTP material can be valued.
