the lethality of pulsed ultra-violet (uv) rich light for the inactivation of pathogenic bacteria has been investigated. a low pressure xenon filled flash lamps that produced uv intensities have been used. the pulsed operation of the system enable the release of electrical energy stored in the capacitor into the flash lamp within a short time and produces the high current and high peak power req...
A flashlamp-pumped dye laser was modified to produce 80mJ/pulse, narrowband output at 532 nm suitable for pumping of Raman active transitions of the major combustion species CO2, H2O, N2, and O2. Simultaneous measurements of multiple species were obtained in atmospheric pressure methane-air flames, demonstrating absolutely quantitative measurements of species mole-fraction. Comparisons with Q-s...
Two standard commercial flashlamp-pumped Nd:YAG (YAG denotes yttrium aluminum garnet) lasers have been upgraded to "pulse-burst" capability. Each laser produces a burst of up to 15 2 J Q-switched pulses (1064 nm) at repetition rates of 1-12.5 kHz. Variable pulse-width drive (0.15-0.39 ms) of the flashlamps is accomplished by insulated gate bipolar transistor (IGBT) switching of electrolytic cap...
The principle of laser action was first experimentally demonstrated in 1960 by T. Maiman (Maiman, 1960). This first system was a solid-state laser in which a ruby crystal and a flashlamp served as gain medium and pump source, respectively. Soon after this first laser experiment, it was realized that solid-state lasers are highly attractive sources for various scientific and industrial applicati...
