Abstract
We have developed a novel method to correct the spatial distortion resulting from temporally stretching/compressing optical pulses with a chirped volume holographic grating (CVHG) in glass. We show that the inherent spatial beam distortion can be corrected to produce a distortion-free round beam output. We fabricated a 30 mm long CVHG with 9 nm bandwidth, 300 ps delay at 1031nm exhibiting a smooth round spatial Gaussian profile after compression. Coupling efficiencies for the compressed pulse exceeds 75% into a single mode fiber. The spatial profile is maintained over a wide temperature range from 10 to 60 degrees Celsius. We believe that the spatial beam profile improvements of CVHG demonstrate herein enables the practical realization of ultra-compact and efficient chirped pulse amplification laser systems.
