Noise-like Pulses as a Source of Pump Energy

Abstract

This work analyses application particulars of noise-like pulses used as pulsed pump radiation for lasers (including Raman lasers) and amplifiers. The absence of a phase relationship between the electromagnetic field of the pump and that of the output laser radiation allows for a new application as a pump energy source of noise-like pulses, which may feature relatively high energy parameters. Questions related to this application are considered: configurations for noise-like pulse generation that hold a significant potential, specific aspects of amplification and compression, and characterisation of parameters of these pulses. Possibilities of the efficient application of noise-like pulses as pico- and nano-second pumping radiation are also discussed.
