Title: High Average Power-Green Laser for Synchronous Photoinjection
Agency: DOE
Contract: DE-FG02-06ER84491
Award Amount: $99,998.00
 

Abstract:

A high-quantum-efficiency long-lifetime photocathode is a key component for the synchronous photoinjection of GaAs photoemission guns, used in modern particle accelerators. High-power pulsed-laser sources, with picosecond pulse durations at GHz repetition rates, are needed to provide enough power to enable this application; yet, none are commercially available. This project will develop a highly efficient, high-average-power (~100 W) green laser source, based on second harmonic generation of a high power fiber laser, with variable pulse durations and repetition rates. This fiber-laser-based approach will provide a reliable, capable, cost-efficient, and extremely versatile laser light source to improve the performance of DOE┬┐s accelerators. Phase I, will design and construct an efficient front end for the laser source and demonstrate the flexibility of the high-rep-rate and short pulse waveforms. The front end will use fiber components and inline connections, with no mirrors or free-space propagation in the optical design. The front end developed in Phase I will provide enough power for the Phase II amplification and frequency conversion. Commercial Applications And Other Benefits as described by the Applicant: The high power green laser, combining high power and high brightness with low signal noise at high repetition rates, would have the potential to replace existing mode-locked DPSS lasers for medical, material processing, micromachining, semiconductor processing, and underwater communications
