Abstract
A tunable laser includes a birefringent tuning crystal placed in the laser cavity. An electrical signal is applied to the tuning crystal to establish an electrical tuning field within the crystal, and a desired laser tuning rate as a function of the applied electrical signal is established by rotating the optic axis of the crystal through a selected small acute angle from the direction of the laser light path through the crystal. The tunable laser is included in tunable laser systems for derivative spectroscopy and transient spectroscopy.
