THICK DISC LASER AMPLIFICATION SYSTEM AND USES THEREOF

摘要

The invention concerns a laser amplification system comprising a pumping device and at least one thick amplifier disc having a first face, which is reflective at the wavelengths of a pulsed laser beam of the laser amplification system and of a pump beam of the pumping device, as well as at least one heat-dissipation component to which this first face of the amplifier disc is firmly secured, the saturation fluence of the active medium of the amplifier disc being equal to or less than 3 J·cm−2.

主权项

1. Laser amplification system, of the type comprising:
a plurality of amplifier discs, each of said amplifier discs having a first face which is reflective at the wavelengths both of a laser beam and of a pumping beam, the saturation flux of the active medium of the amplifier discs being less than or equal to 3 J·cm−2; and at least one semiconductor-type pumping device, generating the pumping beam for said amplifier discs, wherein: each of said amplifier discs is a thick amplifier disc; the laser amplification system further comprises at least one heat dissipation element, to which the first face of said amplifier discs is rigidly connected; and said laser amplification system is configured so that the optical path of the pulsed-type laser beam between two amplifier discs is less than fifteen times the diameter of an amplifier disc.
