What Have We Learned from the kilowatt IR-FEL at Jefferson Lab?
Recent work at Jefferson Lab has demonstrated the concept of same cell energy recovery to attain high average power in a free-electron laser (FEL)[1]. Since this device was the first of its kind, we learned a great deal about how to design such systems as we learned to operate the prototype. We are in the process of building a laser with an average power in excess of 10 kW in the infrared and have point designs for even higher power. This talk will summarize the problems which were thought to exist before the IR Demo lased and what we have learned since the laser operated successfully. The upgrade has its own challenges and these will be described and the proposed solutions will be described. The changes required in the electron beam transport [2] will be summarized. A new optical cavity has been designed which allows much higher power than the IR Demo. The design details will be covered.
