The JAERI free-electron laser driven by a superconducting rf Linac towards ultra-short pulse, highly-efficient, high power, and tunable coherent light sources

Minehara, Eisuke

We would like to explain reccent developments and future plans of the JAERI(Japan Atomic Energy Research Institute) free-electron lasers driven by a superconducting rf linac with an energy recovery loop. In the beginning of February 2000, we could exceed our 1-kW design goal and finally reach 2.34kW in quasi-continuous wave(CW) operation with a very high extraction efficiency of 5 percent or more. The high power and highly-efficient lasing has recently been found to be a novel one, a few cycle lasing of 250fs, and about 1 GW peak at the perfect synchronism without lethargy.
