All-Solid-State Tunable Ti∶Sapphire Laser with High-Power and Single-Frequency at 900 nm
By pumping the Ti∶sapphire crystal cutted by the Brewster angle with a homemade all-solid-state high-power 532 nm single-frequency green laser, we design a compact, stable and self-compensating embedded six-mirror ring resonator structure. By adjusting the best mode matching relationship between pumping light and oscillating light, we establish an all-solid-state single-frequency tunable Ti∶sapphire laser with high beam quality and high conversion efficiency at 900 nm. With the pump power of 15 W and the output mirror fixed point transmission of 4.5% at 922 nm, the broadband tunable single-frequency infrared laser with average output power of more than 2 W and tunable wavelength range from 852 nm to 934 nm is obtained. The power stability is better than ±0.7% within 3 h and the beam quality factor M2 is less than 1.04.
