M. Villagranmuniz et al., PHOTOACOUSTIC ANALYSIS OF STIMULATED-EMISSION IN PULSED DYE-LASERS, Applied physics. B, Lasers and optics, 61(4), 1995, pp. 361-366
Stimulated emission in pulsed dye lasers was characterized in several
experimental conditions by analyzing the changes in the acoustic signa
ls generated in a dye solution, with the dye laser cavity either activ
e or inhibited (i.e., by blocking the optical path or misaligning of t
he optical components). Pump energy threshold, optimum dye concentrati
on, tuning range and maximum-emission wavelength of a rhodamine 6G dye
laser were measured by this method. An approximate model for the phot
oacoustic signal generation consistent with the experiments is present
