TUNABLE SINGLE-MODE PULSED TI3-SEEDED BY A CONTINUOUS-WAVE CR3+LISRALF6 LASER(SAPPHIRE LASER INJECTION)

Spectrally pure high-power tunable single-made operation oi a pulsed T i3+:sapphire laser by a tunable injection-seeding is reported. The inj ection laser was a cw diode laser pumped, spectrally narrowed tunable Cr3+:LiSrAlF6, (Cr3+:LiSAF) laser with a grating in the auxiliary cavi ty. Single-mode tunable operation of a pulsed Ti3+:sapphire ring oscil lator was obtained at different wavelengths in the range between 818 n m and 848 nm with a typical linewidth of 0.006 cm(-1). To extend the a pplicability of this operation to a differential absorption lidar syst em, the single-mode Ti3+:sapphire oscillator output was amplified and a high energy output of 38 mJ was obtained with the same linewidth.
