The problem of oscillation, amplification and transformation into shortwave region of spectrum of a pulsed IR chemical hydrogen fluoride laser radiation a nanosecond time scale is considered. On the basis of computer calculations the conditions for obtaining the effective oscillation and amplification of HF chain reaction laser pulses with pulse length of the order of 10-8s are revealed. It is offered to exite by this pulses the active medium of eximer lasers. The threshold intensity of IR radiation for KrF laser is found. The efficiency of [MATH] transformation of radiation is also calculated. The possibility of principle to create a pure chemical amplifier of short pulsed IR radiation, in which the reaction is initiated by the optical discharge in the field of input signal, is shown.
