title: Injection-seeded, gain-switched tunable Cr:ZnSe laser.
abstract: We report a narrow-linewidth, tunable, gain-switched Cr:ZnSe laser operating between 2255 and 2455 nm. The spectral width of the laser was reduced from 125 nm to 0.3 nm by using injection seeding. Seeding was achieved with a second tunable CW Cr:ZnSe laser. The output wavelength was varied by tuning the wavelength of the seed laser. The seeded oscillator produced as high as 157 µJ pulses with 598 µJ incident pump pulse energy at a repetition rate of 1 kHz. The slope efficiency was determined to be 26%.
