AbstractThe bone ablation characteristics of five infrared lasers, including three pulsed lasers (Nd:YAG, λ = 1,064 μm; Hol:YSGG, λ = 2.10 μm; and Erb:YAG, λ = 2.94 μm) and two continuous‐wave lasers (Nd:YAG, λ = 1.064 μm; and CO2, λ = 10.6 μm), were studied.

Infrared laser heterodyne systems
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2004This paper gives a review of mid-infrared laser heterodyne systems. The advantages of using heterodyne detection are described and the different techniques corresponding to the choice of the local oscillator are presented. A thorough discussion of the gas laser heterodyne systems is followed by the presentation of tunable diode laser systems ...

Scanned Laser Infrared Microscope
Applied Optics, 1970In examination of ir-transmitting materials, internal irregularities and inclusions of foreign material can be detected by their effect upon the ir transmittance of the material. A scanning laser ir microscope has been constructed which produces, on an oscilloscope display, a shadowgraph picture of the ir transmittance of the material under examination.

Abstract Two far i.r. lines from a pulsed helium laser have been accurately measured with a metal grid Fabry-Perot interferometer at wavelengths of 95.763 ± 0.006 μm and 216.12 ± 0.01μm. The laser output critically depends on the plasma conditions in the laser during the excitation phase.

An hydroxyl radical infrared laser
Chemical Physics Letters, 1971When mixts. of O3 and mol. H2 were flashed in a laser cavity, stimulated ir emission at 3050-3410 cm-1 was detected, and the radiation was identified as the P1 transitions of the v = 3 -> 2, 2 -> 1, and 1 -> 0 fundamentals of the OH radical. Stimulated emission was obsd. with flash energies of 400-2000 J, for O3/H2 mixts.

Interaction of far-infrared and mid-infrared laser transitions in the NH3 laser
Applied Physics Letters, 1980Laser emission on the conventional 12.8-μm NH3 laser transition, optically pumped by the CO2 9R16 line, can be completely quenched and replaced by emission at 12.2μm. Cascading far-infrared laser transitions in the excited ammonia ν2 state are shown to be responsible for the shift in wavelength.

The current state of the art in mid-infrared fiber lasers is reviewed in this chapter. The relevant fiber-host materials such as silicates, fluorides, chalcogenides, and ceramics, the fiber, pump, and resonator geometries, and the spectroscopic properties of rare-earth ions are introduced. Lasers at transitions ranging from 1.9 to 4 μm occurring in the

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1985
Abstract Successful production of microwave radiation by Cherenkov masers has prompted an investigation into their feasibility for submillimeter and far infrared wavelength generation. A theoretical examination of output parameters such as frequency and small signal gain has been conducted for an easily fabricated resonator geometry.
