Free Electron Lasers (FEL) Sources
Free-Electron Laser (FEL) sources can produce high-power,
tunable radiation in intense pulses across a large portion of the electromagnetic
spectrum. AES FEL-related activities range from mm-waves to X-rays. AES
designed, fabricated and operated the Compact Infrared FEL (CIRFEL) at
Princeton University, making us one of the very few companies that have
succeed in obtaining FEL lasing on their own equipment removed from National
Laboratory facilities and assistance. We also supported the design and
fabrication of the 10 kW IR Upgrade FEL at the Thomas Jefferson National
Accelerator Facility (JLAB) and are active in many aspects of the ongoing
Navy FEL program.
| CIRFEL
Compact, affordable free-electron lasers, such
as the CIRFEL, which originally operated at Princeton University
and is being reassembled at the University of Maryland, can provide
high-peak-power, tunable radiation for research, medical, biomedical
and material processing applications. The particular advantage
of such photocathode-accelerator-driven FELs for these applications
is their high brightness and picosecond pulse structure which
yields very high peak dose with efficient energy deposition and
minimal collateral damage. The broadband tunability of FELs permits
the excitation of resonance phenomena and generates many different
uses. AES is developing these devices for the surface treatment
of materials, near-field IR microscopy, biomedical and other applications.

| JLAB IR FEL Upgrade
Amongst other activities, AES supported the design
of the bending magnets for the JLAB IR Upgrade FEL (link here
to magnet analysis picture) and designed and fabricated the optical
klystron wiggler, in conjunction with Laboratory personnel, used
in the recent 8.5 kW CW IR demonstration at 6 microns (check it
was 6). We also completed the engineering design and procurement
of the high-power THz beamline that was recently commissioned
at the FEL and are about to deliver a 100 mA-capable electron
injector for assembly and testing that will serve as the driver
for a next-generation 100 kW-level FEL (link to DC gun and booster
plus papers).

| Navy FEL Program
AES is active in various aspects of the ongoing
Navy FEL program. Specific specialties are the high-current injectors
(links to injectors) and the high-power RF couplers needed for
these devices, and the systems modeling of systems configured
for Navy applications.
