Ring-laser configuration with spontaneous noise reduced by destructive interference of the laser outputs

Physical Review A, 1990
Thin layered gain media in a ring cavity can lead to detection devices free of spontaneous-emission noise. A theoretical analysis and a physical explanation for the destructive interference of the spontaneous emission in one of the laser outputs are presented.

Laser-ultrasound-based non-destructive testing—optimization of the thermoelastic source

Measurement Science and Technology, 2015
Laser-ultrasound-based non-destructive testing (NDT) applications usually use circular or linear thermoelastic sources. This paper studies two more complex sources and presents their specific advantages. The first thermoelastic source is a regular line array, whereas the second one is a chirped line array.

Biological tissue destruction under laser irradiation

Journal of Engineering Physics and Thermophysics, 1993
Physical processes proceeding in a biological tissue under laser irradiation are described. Based on evaluation of all heat-mass transfer processes, a model of biological tissue destruction is proposed as the multiboundaryvalue Stefan problem with stepwise variation of thermophysical parameters at phase boundaries.

NON-DESTRUCTIVE LASER SORTING OF WHOLE TOMATOES

Acta Horticulturae, 2005
Spectroscopy techniques are used as non-destructive optical methods for evaluating the internal quality of many horticultural products. Laser-based visible spectroscopy is an appropriate tool for tomato analysis. There is a great change in the visible reflectance and transmittance spectrum of the tomato as it matures, so internal properties such as ...

Laser active thermography for non-destructive testing

SPIE Proceedings, 2013
Thermography methods have found their applications in different fields of human activity. The non-destructive feature of these methods along with the additional advantage by automated remote control and tests of nuclear installations without personnel attendance in the contaminated zone are of particular interest.
