Abstract :
FEL lasing with the saturated power in the wavelength of 4–16 μm was achieved by using the KHI (Kawasaki Heavy Industries, Ltd.) FEL device. The macro-pulse length of the electron beam was improved by using the LaB6 cathode instead of the dispenser cathode as a cathode of the OCS RF-gun. The improvement yielded the saturated FEL power with the macro-pulse length of 0.5–1.5 μs. The FEL energy was 2–40 mJ. The measured FEL output powers were in agreement with the values which were taken into account Piovella’s theory.
