Evolution of Orbital Angular Momentum Spectrum of Broadband Laguerre-Gaussian beam in OPCPA proces
Listed in ScienceDB
In this study, we numerically simulate the evolution of the orbital angular momentum (OAM) spectrum of a vortex laser beam in the optical parametric chirped pulse amplification (OPCPA) process, which is an effective technical method to realize ultra-intense and ultra-short vortex laser amplification.
Description
The results show that the proportion of the vortex laser beam with 100% topological charge (TC) of 1 decreases to 97.44% with the enhancement of the saturation amplification after amplified by a 15 mm length LBO pumped by a 526.5 nm laser with a pump intensity of 1.74 GW/cm2.
Conversely, the beams with other topological charges generate and increase with the amplification. The simulation results are consistent with our previous experimental results. Meanwhile, compared with non-collinear OPCPA, collinear OPCPA can maintain well the proportion of TC l=1.
