Optical amplifier - arrangement, lasers - amplifier - system and method for generation of a wide to infrared visible, at least close to - infrared spectrum of coherent ultra - short light pulses with an optical amplifier - arrangement
Optical amplifier - arrangement, lasers - amplifier - system and method for generation of a wide to infrared visible, at least close to - infrared spectrum of coherent ultra - short light pulses with an optical amplifier - arrangement
The invention relates to an optical amplifier - arrangement of optical parametric amplifiers and white light - generations and a and harmonic - generating, in particular frequency doubling, for the generation of a wide to infrared visible, at least close to - infrared spectrum of coherent ultra - short light pulses, in particular with a pump - laser, as well as a method for producing a wide visible to infrared, in any case of nah - infrared spectrum of coherent ultra - short light pulses with an optical amplifier - arrangement. According to the invention it is provided that, during the operation, the fundamental in a wavelength range above 950 nm, and the second signal - light and the second idler - light of the second optical parametric amplifier by tim mbar together a speed range of wavelengths between 500nm and 5µm, in particular between 550 nm and 3 μm, covering, wherein between wavelengths in the by tim mbar continuous speed range can be continuously tuned, in particular can be continuously tuned by means of the degeneration region of the second optical parametric amplifier (opa2) in the case of the fundamental, preferably of the pump - laser.
