An optical amplifier arrangement has optical parametric amplifiers and white light generations and harmonic generation, in particular frequency doubling, for generating a wide visible to infrared, in any case near-infrared, spectrum of coherent ultra-short light pulses, in particular with a pump laser. During operation the fundamental is in a wavelength range above 950 nm, and the second signal light and the second idler light of the second optical parametric amplifier together cover a tunability range of wavelengths between 500 nm and 5 &#x3bc;m, in particular between 550 nm and 3 &#x3bc;m, wherein between wavelengths in the tunability range throughout continuous tuning can be carried out, namely through the degeneration range of the second optical parametric amplifier at the fundamental of the pump laser.

Optical amplifier arrangement, laser amplifier system and process

A method of and an optical arrangement for generating a non-linear optical signal on a material excited by an excitation field, wherein with the excitation field coherent fields of first and second optical pulses of differing frequency are overlapped in the material in temporal and spatial relationship, wherein the first pulses of a first frequency are generated in a first beam of a first optical generator unit, and the second pulses of a second frequency are generated in a second beam of a second optical generator unit synchronously pumped by the first optical generator unit, wherein with the first pulses of the first frequency as a fundamental frequency pulses of a higher harmonic frequency thereof are generated and the second optical generator unit is pumped with the pulses of the higher harmonic frequency.
