Compact fiber CPA system based on a CFBG stretcher and CVBG compressor with matched dispersion profile

Abstract

In this work, a compact fiber chirped pulse amplification system exploiting a tandem of a chirped fiber Bragg grating stretcher and a chirped volume Bragg grating compressor with matched chromatic dispersion is presented. Chirped pulses of 230 ps duration were amplified in a Yb-doped fiber amplifier and re-compressed to 208 fs duration with good fidelity. The compressed pulse duration was fine-tuned by temperature gradient along the fiber Bragg grating stretcher.

Optimization of a supercontinuum source based on tapered ordinary fibers

“…The pulses were then stretched using a tunable chirped fiber Bragg grating (CFBG) from 1.5 ps to 480 ps and amplified in two fiber amplification stages that were pumped with laser diodes at 976 nm [30], [31]. The repetition rate of the pulses in the second amplification stage was controlled using an acousto-optic modulator (AOM) [20].…”

Adaptive Nonlinear Phase Compensation in a Femtosecond Hybrid Laser with Varying Pulse Repetition Rate

“…It was recently shown that a tunable chirped fiber Bragg grating (TCFBG) can efficiently compensate nonlinear phase up to 4π [12]. As a TCFBG can also be used as a pulse stretcher in a chirped pulse amplification technique (CPA), its use for nonlinear phase compensation offers a clear advantage in terms of compactness and robustness compared to the use of spatial light modulators (SLM-s) or other pulse-shaping techniques [30][31][32][33][34][35][36].…”

Mid-infrared fiber laser : high-power ultrafast pulse delivery and compression

“…Lastly, the pulse compression quality can be further improved by using a matching pair of tunable CFBG and CVBG [105]. The tunability of the 2 nd , 3 rd , and 4 th -order dispersion of the CFBG allows dynamic pre-compensation of the high-order dispersion and nonlinear-induced phase shift.…”
