Abstract

A variety of progress concerned with an electronically tuned Ti:sapphire laser with an acousto-optic tunable filter for the purpose of spectroscopic applications are described. The major advances are that fast and random access tuning can be achieved in a tuning range of 690-1056 nm by computer control without any mechanical changes of cavity. The access speed reached to 250 microsecond(s) . The Ti:sapphire laser also provided tunable dual-wavelength operation in a single laser cavity with introducing two different radio frequencies at same time. The operation was promising as a pumping source of difference-frequency generation. Difference-frequency generation of non-mechanical tuning was realized from 6.0 to 7.1 micrometers , from 6.8 to 8.6 micrometers , and from 8.5 to 11.3 micrometers for the phase-matching angle at 58, 53, and 46 deg, respectively, using the dual-wavelength laser. Furthermore, the electronic tuning by acousto-optic tunable filter achieved broad tunable picosecond pulse generation with only computer control.
