SPIE Vol. Only in Astigmatically compensated cavities for CW dye lasers Abstract: An analysis is given of folded 3-mirror laser resonators with an internal cell set at Brewster's angle. Volume 14, number 2 OF’TICSCOMMUNICATIONS June 1975 zyxwvutsrq OPTO-ACOUSTIC SPECTROSCOPY WITH A VISIBLE CW DYE LASER A.M. ANGUS, E.E. A procedure has been developed to tune the laser to the wavelength of any molecular absorption line in the 565-620 nm spectral region. Passive mode locking of a cw Rhodamine 6G laser is reported. The effect of cooling the laser medium on the lasing characteristics of an organic cw dye laser, Rhodamine B in ethylene glycol, pumped by an Argon laser was examined. The spectral width of the laser emission is less than 3 GHz and can be tuned over more than 30 nm. It plays the premier role as a source of tunable radiation in the visible and near-visible regions of the spectrum. MARINER0 and M.J. COLLES Department of Physics, Heriot-Watt University, Edinburgh, Scotland, Received 1975 first use with an opto-acoustic cell is described. Source: In: Proc. Methods of measuring pulse duration and applications of these CW mode-locked dye lasers for ultra fast spectroscopic studies G.R. An increase of absorption sensitivity by a factor of 10 5 , compared to a single-pass measurement, is observed in an experiment with an iodine vapor absorption cell inside the cavity of a CW dye laser.

PY - 1975/6. 1 Advantages and disadvantages of tunable CW dye lasers The most important advantage of dye lasers is their broad and continuous tun-ability within the visible spectrum. Pulsed dye laser, Behandeling van vaatafwijkingen met Deze informatie is opgesteld door de afdeling(en) Huidziekten. The dye laser is considered to be the first broadly tunable laser. With occasional adjustment the laser will neither drift nor jump off of the desired molecular line. A nearly circular mode profile is achieved with an M2 better than 1.4. In this letter a frequency-doubled frequency-stabilized CW ring dye laser for the wavelength region 292-305 nm is described. FLEMING, G.S. Loading ... 1 megawatt TE N2 laser pump a Dye laser - Duration: 2:39. rocketman340 8,080 views. A cw dye laser is described that provides tunable, high-power single-frequency radiation over the entire visible spectrum. T1 - A grating tuned cw dye laser. Cytometry. Frequency Stabilization of a CW Dye Laser Frequency Stabilization of a CW Dye Laser 1974-12-01 00:00:00 In order to perform ultrahigh resolution spectroscopy, a tunable laser with a narrow spectral width is required. This is to orient the measurements of the HFS splitting with high resolution fluorescence spectroscopy. A method is described to compensate the astigmatic distortions introduced by both the internal mirror and the cell. The properties of passively and actively mode-locked dye lasers are described and compared. Laser Type Wavelength CW or Pulsed Output Power Applications ArF, Krf, XeCl, Xef Gas (excimer) 193 nm, 248 nm, 308 nm, 353 nm ns 10 W: UV lithography, laser surgery, LASIK, laser annealing: Nitrogen Gas 337 nm ns 100 mW: Dye laser pumping, measuring air pollution: Dye Liquid 400-1000 nm CW-fs 1 W: Spectroscopy, laser medicine: GaN Cw dye laser synchronously pumped by the third harmonic of a mode-locked cw Nd:YLF laser for tunable blue and green excitation and picosecond time-correlated photon counting detection. All other lasers, be they solid state or gas lasers, can only be tuned within a narrow band or emit only at discrete wavelengths. spectra physics 375 cw dye laser pumped with a 5W argon ion laser rocketman340. Studies on cw dye laser 715 In the above equations G, = aphV/ 2 is the maximum available gain expressed in terms of absorption cross-section of the dye at the pump wavelength a,, the total population density of the dye N, and length of the gain medium 1. BEDDARD Continuously working dye lasers have produced pulses as short as 0.3 ps. 500 μW U.V. An intense, frequency stable, multi-mode, standing wave cw dye laser of variable bandwidth (0.5 to 3 GHz) and large tuning range (>400 GHz) is described. 5) The cw-dye laser must be capable to lasing in a wide range (≈ 50 GHz) of single frequency scan. A dual laser flow sorter has been constructed from an existing single laser system by incorporating a dye laser as the second laser source. 1640 - p. 325 - 329. Experiments have been carried out on the injection-locking of a pulsed dye laser to an argon-laser-pumped CW dye laser of 50 MHz linewidth without longitudinal mode matching. The laser resonator of a dye laser typically contains a dye jet or a dye cuvette (see below) as the laser gain medium.
