Abstract

A new concept of the direct amplification of femtosecond optical pulses in photochemically driven active media, such as Xe₂Cl, XeF(C–A) and Kr₂F, is discussed with the main emphasis on the XeF(C–A) active medium as one of the most widely studied system. The main advantage of these systems is that they are characterized by a broad gain bandwidths (60–100 nm) which allow to support 10 fsec pulses and are centered in the blue-green region (490, 480 and 420 nm, respectively) spectrally matching to the second harmonic of a Ti:Sa laser. The last circumstance is important from the viewpoint of considerable increasing temporal contrast ratio of ultrahigh peak-power fsec systems.
