Temporally stable hybrid dyehyphen;Ti:sapphire laser by selfhyphen;induced gain switching

摘要

A novel simple Nd:YAGhyphen;laserhyphen;pumped pulsed hybrid dyehyphen;Ti:sapphire laser is described. A spectral linewidth of 0.28 nm is selected near threshold and tuned from 705 to 770 nm in a compact (15hyphen;cm long) cavity. When the threshold is exceeded by a factor of 1ndash;3, the jitter in the onset of the Ti:sapphire laser pulse is reduced to 10 ns. This is about 7percnt; of the 140hyphen;ns jitter for a pure Ti:sapphire laser under equivalent conditions. The result is achieved via accelerated gain switching in the Ti:sapphire induced by intracavity injection of radiation from the dye.
