Simple method of measuring laser peak intensity inside femtosecond laser filament in air.
Measurement of laser intensity inside a femtosecond laser filament is a challenging task. In this work, we suggest a simple way to characterize laser peak intensity inside the filament in air. It is based on the signal ratio measurement of two nitrogen fluorescence lines, namely, 391 nm and 337 nm. Because of distinct excitation mechanisms, the signals of the two fluorescence lines increase wit...
متن کاملIridotomy with a ruby laser.
Extensive experience with animals has shown that it is possible to irradiate the iris with a ruby laser without damage to the cornea, lens, or retina (Hallman, Perkins, Watts, and Wheeler, I 968, I969). The possible use of a laser to make an iridotomy for therapeutic purposes was appreciated by Flocks and Zweng (i964), and Zweng, Flocks, Kampany, Silbertrust, and Peppers (I964) reported two att...
متن کاملMeasuring cardiac output: intermittent bolus thermodilution method.
cialist in the cardiac care unit and cardiac observation unit at UCLA Medical Center and is an assistant professor of nursing at the UCLA School of Nursing, Los Angeles, Calif. by a computer and converted into a measurement of cardiac output. Cardiac output is inversely proportional to the area under the curve. The normal cardiac output curve has a rapid smooth upstroke and a gradual downstroke...
متن کاملPulse stretching in a Q-switched ruby laser for bubble chamber holography.
In testing a holgraphic particle track recording system for the Fermilab 15-ft bubble chamber, it was shown that the peak power of Q-switched laser pulses (50-ns duration) at the required energy gave rise to boiling during the chamber expansion. A pulse stretching technique is described which was developed to reduce the peak power. Applied to a ruby laser (oscillator and three amplifiers) with ...
متن کاملRuby laser transmission and the lens.
The earliest recorded study of the transmission of light by the ocular *media is attributed to Aschkinass (1895), but according to Meyer-Schwickerath (I960) his method was grossly inaccurate. Luckiesh (I92 I) calculated the transmissivity of the ocular media on the basis that it equalled that of a layer of water 2-28 cm. thick. Shoji (1923) and Bucklers (I926) both made measurements of transmis...
