Electronically tuned pulsed dye laser

The development of an electronically tuned pulsed nitrogen laser pumped dye laser is described. Tuning of the laser is achieved by electronic coupling of a piezo ("inchworm") driven grating with a piezo driven etalon. Tuning over a range of 180 GHz has been obtained with a laser line width of 250 MHz. A description of the apparatus and representative spectra obtained with the laser are given.
