Large-Scale, High-Efficiency Transmission Grating for Terawatt-Class Ti:Sapphire Lasers at 1 kHz

Large-Scale, High-Efficiency Transmission Grating for Terawatt-Class Ti:Sapphire Lasers at 1 kHz

A novel transmission grating with a large scale (170 mm long, 40 mm high, and 1 mm thick) has been developed. The diffraction efficiency is over 93% and is almost flat from 750 to 850 nm. We developed a 1-kHz, 10-mJ, 0.5-TW Ti:sapphire laser system by using transmission gratings in a compressor. The...

Zusammenfassung:A novel transmission grating with a large scale (170 mm long, 40 mm high, and 1 mm thick) has been developed. The diffraction efficiency is over 93% and is almost flat from 750 to 850 nm. We developed a 1-kHz, 10-mJ, 0.5-TW Ti:sapphire laser system by using transmission gratings in a compressor. The throughput of the compressor was about 70%. The large-scale grating is capable of increasing the peak power up to multi-terawatts at 1 kHz.
