A compact two-cuvette dye amplifier capable of pulse amplifying weak cw visible sources by factors in excess of 10[sup 9] has been demonstrated. Seeded with a 300-[mu]W single-frequency He--Ne laser and without the need for a Faraday isolator, the preamplifier yields [lt]40-[mu]J pulses of 4.5-ns duration and 1.4[times] transform-limited linewidths around 140 MHz. Subsequent power amplification yields 4-ns FWHM, 2-mJ pulses with excellent pulse-to-pulse stability and linewidths around 170 MHz. Scaling of the operational envelope and extension to pulse amplification of cw single-mode tunable diode lasers is discussed.
