Title: Concepts for UV-FEL optics

Abstract

Brookhaven National Laboratory has developed a design for an ultra-violet free electron laser facility utilizing a seeded amplifier approach. Since the accelerator is a single pass device, resonator and outcoupler mirrors which are a difficult aspect of oscillator FEL designs are not required. The result is a source of high peak power VUV radiation with the mode structure, bandwidth and frequency stability of the input seed laser. The accelerator provides pulses of radiation at up to 10 kHz, so to maximize the utilization of the source, novel optical systems to share the radiation had to be developed. These include specialized alignment, beam transport, order sorting, and multiplexing optics. In addition, FEL on FEL pump-probe experiments are made possible by a variable optical delay of up to 10 ns operating in the wavelength range of 200 to 75 nm. Some aspects of the FEL design are also described to clarify the constraints and choices for the optical system.
