Amplifier of energy of femtosecond laser pulses with different temporal intensity profile

摘要

The proposed useful model refers to femtosecond laser systems with a high radiation power. The energy amplifier of femtosecond laser pulses with a different temporal intensity profile comprises a primary laser source, one or more active reinforcing elements made of a chromium forsterite doped with chromium ions, a mirror system to allow laser radiation to pass through an amplifier configured to repeatedly pass laser radiation through active amplifying elements and pumping lasers of active amplifying elements, characterized in that it comprises a driver spectrum of the laser pulse to obtain the required temporal intensity profile and telescopic systems for correcting the divergence of the laser radiation and pump lasers of the active amplifying elements. The technical result consists in increasing the energy of femtosecond laser pulses with a central wavelength λ = 1240 nm and with a different time profile of the pulse. 1 z.s. f-ly, 1 il.
