METHOD AND DEVICE FOR CONTROLLING THE AMPLITUDE OF THE WAVELENGTH SPECTRUM OF ULTRA-SHORT LIGHT PULSES EMITTED BY MULTIPASS LASER AMPLIFIERS |
摘要 |
The invention relates to a method and device for controlling the amplitude of the wavelength spectrum of ultra-short light pulses emitted by multipass laser amplifiers. According to the invention, a programmable acousto-optic device (8) is introduced into a laser cavity of a multipass amplifier (10), in order to modify slightly the amplitude of the spectrum of the light pulse with each passage, owing to a collinear or quasi-collinear interaction between the light pulse and a sound beam, the result from the filtering being used on the non-diffracted direct light beam from the acousto-optic interaction. |
