with an available laser to generate output at a wavelength longer than that of the pump . For example, the CO 2 laser has long been used to generate far - infrared coherent radiation from optically pumped gases ...
spectroscopy. Optical Engineering 32(10), 2460â2463 (October 1993). 1 Introduction Far - infrared (FIR) lasers are frequently used in plasma diagnostics, molecular spectroscopy, and solid state material through ...
An optically pumped molecular laser system with a transverse excitation scheme has been used to generate far - infrared radiation. Over 100 laser emissions with wavelengths up to 1.03 mm have been ...
A molecular far - infrared (FIR) laser optically pumped by a high-power CO2 laser , which is a powerful source for testing detectors and mixers and for FIR spectroscopy, is constructed ...
In order to produce ultrashort far - infrared (FIR) laser pulses we have investigated the superradiance and Raman emission of various molecular transitions optically pumped with the pulses of 10 ...
, it is important to know the gain of the laser . Most optically pumped far - infrared lasers (OPFIR`L) have a circular cylindrical waveguide, where the pump beam is focussed into the resonator through a small hole in ...
In order to produce ultrashort FIR laser pulses we have investigated the superradiance and Raman emission of various molecular transitions optically pumped with the pulses of 10 micrometers hybrid ...
Using an optically - pumped far - infrared laser as a light source, the far - infrared optical constants of liquid acetonitrile, methanol, dichloromethane, and chlorobenzene were obtained by measuring ...
