The argon ion laser (488-514.5 nm), frequency-doubled NdiYAG laser (532 nm), and dye laser radiation (585 nm) in the coagulative treatment of cutaneous vascular lesions such as port wine stains (Mordon et al, 1993). 

The overall rate constant k was measured at 298 K by following the PH2 absorption from pulsed dye laser radiation at 455 nm during the flash photolysis of PH3 (0.3 to 0.5 Torr) in the presence of N2 (3 to 610 Torr). k increased by a factor of 8 when the N2 pressure was increased from 3 to 610 Torr [13]. A few explicit data for k were later given [27] ...

As is well known, the first-order Doppler effect can be eliminated by irradiating a well-collimated atomic beam perpendicular to a laser beam. Since tunable, narrow-band cw dye laser radiation of sufficiently short wavelength is not yet available, in most cases the excitation of atomic Rydberg states by a one-photon transition from the ground state is not feasible. The population of Rydberg states, however, might proceed from excited, metastable or even short-lived states which are continuously pumped by an additional laser beam. The latter approach was chosen by... 

The dyes for the UV spectral range (below 380-400 nm) are not photochemically stable. In most analytical applications, intense UV radiation below 360 nm is obtained by nonlinear optics, i.e., the generation of harmonics and sum frequencies of the visible dye laser radiation in nonlinear crystals. The most widely employed crystals are KDP. ADP, LiF, LilOs, and BBO. For example, the second harmonic of a rhodamine dye laser (fundamental band near 640 nm) is a more practical way to obtain tunable UV radiation near 320 nm rather than direct lasing of an unstable UV dye laser. 

By using an intracavity frequency-doubling crystal or an external enhancement cavity [8.71,72] continuous frequency doubling and mixing can also be achieved for cw dye laser radiation. Powers of several mW can then be achieved (Fig. 8.28).
