Up to 85-W 1030-nm Fiber Laser Synchronized to 800- and 1550-nm Femtosecond Lasers at 79.5 MHz

Abstract

We achieved high-power synchronized multicolor ultrashort lasers by spectral fraction amplification and master-slave laser configuration at 79.5-MHz repetition rate. The amplified high-power laser pulses at 1030 nm were synchronous to 800-and 1550-nm laser pulses with the timing jitter of 7.7 and 56.5 fs, respectively. Synchronized frequency-doubled femtosecond green light with 16.7-W average power was obtained.Index Terms-Doped fiber amplifiers, fiber nonlinear optics.

Recent Developments of Quantum Dot Materials for High Speed and Ultrafast Lasers

“…Due to their high-power density, high repetition frequency, and narrow pulse duration, the ultrashort pulse lasers can be used in the fields of medical imaging, space ranging, laser weapons, material processing, optical fiber communication, and confidential measurement [ 184 , 185 , 186 , 187 , 188 ]. Ultrashort pulse lasers have mainly been achieved by the active and passive mode-locked methods.…”

High-power pre-chirp managed amplification of femtosecond pulses at high repetition rates

“…The chirp-pulse amplification (CPA) technique, as a straightforward approach to power-scale ultrashort pulses, has been widely studied and used in many laser systems [5,6]. However, owing to the gain narrowing effect and residual high-order dispersion, the shortest pulse duration generated in fiber CPA systems is so far limited to the value of 100 fs [7].…”
