CW laser using a solid polymer medium. Correlation measurements using second‐harmonic generation (SHG) have determined the pulses to be as short as 1.5 psec. 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. Keywords: CW dye laser, single-frequency, linewidth, smooth frequency scan A single-frequency CW dye laser (SF-CW-DL) is a traditional source of a narrow-band smoothly wavelength-tuned radia-tion in the visible spectrum. These characteristics are realized in the present development of high power and single frequency stabilized ring dye laser system. In this letter a frequency-doubled frequency-stabilized CW ring dye laser for the wavelength region 292-305 nm is described. FLEMING, G.S. power combined with a 2 MHz linewidth and a 7 GHz scanwidth has been obtained by intracavity frequency doubling in an ADA crystal. The pulses are transform limited and are wavelength tunable over the range 5900–6100 Å. Based on a pilot study with CW dye laser treatment of PWS, we wanted to investigate whether CW dye laser would be more beneficial in PWS treatment than argon laser treatment. MARINER0 and M.J. COLLES Department of Physics, Heriot-Watt University, Edinburgh, Scotland, Received 1975 first use with an opto-acoustic cell is described. A cw dye laser is described that provides tunable, high-power single-frequency radiation over the entire visible spectrum. This is to orient the measurements of the HFS splitting with high resolution fluorescence spectroscopy. Arndt-Jovin DJ, Grimwade BG, Jovin TM. AU - Marinero, E. E. AU - Angus, A. M. AU - Colles, M. J. PY - 1975/6. Figure 1: Setup of a wavelength-tunable dye laser. With occasional adjustment the laser will neither drift nor jump off of the desired molecular line. The spectral width of the laser emission is less than 3 GHz and can be tuned over more than 30 nm. 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. Abstract.

CW single-frequency ring Dye lasers. CW mode-locked dye lasers for ultra fast spectroscopic studies G.R. This result is obtained from a rate equation model, taking into account the spectral homogeneity, but spatial inhomogeneity of the laser saturation. 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. A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. High-power solid-state cw dye laser. The properties of passively and actively mode-locked dye lasers are described and compared. In addition, there are usually one or several frequency-selective elements, for example a birefringent tuner or a diffraction grating in Littrow configuration, which permits wavelength tuning in a range of tens of nanometers. In this paper we describe a single-frequency jet stream cw dye laser that is carefully designed to minimize high frequency laser jitter. The resonator of 70 to 100 cm length is a symmetric Z-configuration with the dye jet in the center and with a Lyot-filter and one thin etalon as colour and bandwidth selecting and tuning elements. All these lasers can also emit light in a pulsed wave mode. A nearly circular mode profile is achieved with an M2 better than 1.4. 1640 - p. 325 - 329. 1. Online ISSN : 1349-6603 Print ISSN : 0387-0200 ISSN-L : 0387-0200 All other lasers, be they solid state or gas lasers, can only be tuned within a narrow band or emit only at discrete wavelengths.

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. http://www.radiant-dyes.com/PDF/Accessories_for_cw_Dye_lasers.pdf Volume 14, number 2 OF’TICSCOMMUNICATIONS June 1975 zyxwvutsrq OPTO-ACOUSTIC SPECTROSCOPY WITH A VISIBLE CW DYE LASER A.M. ANGUS, E.E. 500 μW U.V. The cw dye laser is a well-established tool of optical science. A stable continuous output of picosecond pulses has been achieved. The parameter to is the advance A dual laser flow sorter has been constructed from an existing single laser system by incorporating a dye laser as the second laser source. CW lasers are classified into five categories based on the active gain medium such as gas lasers, solid-state lasers, dye lasers, chemical lasers, and semiconductor lasers. It was found that the pump power for a given system is limited to a critical value due to the influence of thermal inhomogeneities. It plays the premier role as a source of tunable radiation in the visible and near-visible regions of the spectrum. Pulsed dye laser, Behandeling van vaatafwijkingen met Deze informatie is opgesteld door de afdeling(en) Huidziekten. This laser has a unique set of capabilities that include broad tunability, high power, and the potential for extremely high Cytometry. 5) The cw-dye laser must be capable to lasing in a wide range (≈ 50 GHz) of single frequency scan. TY - JOUR. Central to the design is the elimination of spatial hole burning and the enhancement of mode competition through the use of a ring resonator and a very-low-loss Faraday-effect device to select a single traveling-wave direction.
