We propose to take advantage of the focalization effect of the pump light by the cylindrical laser rod in a side-pumped Nd:YAG laser (flashlamp or diode pumping) to obtain efficient two-wavelength operation. Under conveniently chosen conditions the f

Background and Objective Low-level light therapy (LLLT) has been revealed as a potential means to improve wound healing. So far, most studies are being performed with irradiation in the red to near-infrared spectra. Recently, we showed that blue ligh

Laser ignition of compressed natural gas–air mixtures was investigated in a constant volume combustion chamber (CVCC) as well as in a single cylinder engine. Laser ignition has several potential advantages over conventional spark ignition system. L

The development of a passively Q-switched Nd:YAG laser is described in quite some experimental detail involving 3 pump diode arrays (70 W, 300 W, 600 W). Emphasis is set on the influence of pump beam profile and optimum fiber diameter on achievable p

This paper is an experimental work of the applied methodical character in which as an attempt to optimize a laser ignition system a systematic study of the best incoupling geometry for the employed Nd:YAG laser was performed. The incoupling geometry
