Abstract
A method of increasing the injection-locking efficiency by external narrow-band radiation relying on a space-frequency separation in a nonlinear absorber (spectral contraster) placed into the high-power dye-laser cavity is proposed. It is shown that this method permits an increase of the energy conversion efficiency into a narrow-band line (∼ 10−3 nm) up to 90% with a laser output energy of about 1 J and a pulse duration of more than 1 µs.
