Chirped laser pulses
WebNov 22, 2024 · The 4-inch, 2.1-J, 800-nm, and 30-fs p-polarized laser pulses are split into two laser beams: 1.9-J FL infrared (800 nm) beam and 100-mJ SH ultraviolet (400 nm) beam. The former is focused onto 4-mm-long slit-shaped gas jet using an (F/20) off-axis parabolic mirror (OAP1) [see ( A )]. WebJun 24, 2024 · A photonic crystal fiber-based chirped pulse amplification delivering 272 fs pulses of 66.4 µJ energy at a repetition rate of 500 kHz is presented, resulting in an average/peak power of 33.2 W/244 MW. A single grating is adopted for the pulse width stretching and compression, which leads to high-compactness and low cost of the system.
