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.Other References
