Measurements of molecular and atomic fluorine laser emissions were done from 2?psi (absolute) to 5?atm to determine pressure-dependent spectral lines. While at low pressures, the atomic transitions are dominant; however, both atomic and molecular transitions are detected simultaneously at atmospheric pressures above approximately 2?atm, where a changeover… (More)
Various lines of atomic fluorine laser have been studied over a wide pressure range for determination of the relative intensity of each pressure-dependent line. In this investigation, the most probable laser pumping mechanisms have been verified.
Some fluctuations in the output power of a copper vapor laser with a 16 mm bore were recorded by varying the excitation frequency from 13 to 33 kHz. The effect arises from the laser tube, which performs both as an optical and an acoustic resonator at the acoustic resonant frequencies. It is shown that a similar effect occurs in other metal vapor and copper… (More)
