A gain-enhancement technique using a higher harmonic cavity has been developed for free electron laser experiments on the UVSOR storage ring. With this technique, we obtained lasing in the ultraviolet region at wavelengths around 300 nm. Applying gain-switching to control lasing, effective gain was derived at a wavelength of 490 nm, which was in good agreement with the theoretical prediction.
