One of the ways of constructing a two-pulse laser emitter with a narrow spectral line, tunable over a wide wavelength range and based on a Ti:sapphire active medium, was investigated. This medium was excited by pulsed second-harmonic radiation of a neodymium glass laser. The parameters of the laser components were determined. These make it possible to construct a two-pulse source of radiation with a line width of {Delta}{lambda} {<=}0.01 A in each pulse, tunable in the range 670 - 1010 nm, and providing means for varying the spectral spacing between the pulses. The amplification of tunable laser radiation was investigated in a single- and four-pass Ti:sapphire amplifier with an axially excited active element 20 mm long.
