ABSTRACT:
The invention is in the field of laser radiation generation in bands II and III, and relates to a device for generating laser radiation in the infrared having means for modifying the amplified-radiation frequency and using the Raman effect, characterized by additionally having at least one diode able to emit laser radiation in the 1.8-2.1 μm frequency range, at least one current generator able to generate current levels at an adjustable repetition rate, means for supplying said current levels to said diode, and means for amplifying the laser radiation emitted by said diode and comprised of at least one fiber doped with an ion having laser activity in the diode emission range.
