We developed a cryogenically cooled Yb:YAG laser as the pump beam for a pulsed Raman laser based on CVD grown diamond crystals. The Q-switched cryogenic Yb-doped YAG 1030 nm pump laser delivered 340 W at 40 kHz with diffraction-limited beam quality,

The spectroscopic detection of complex molecules, such as explosives, requires a much broader spectral tuning range of the employed laser compared to the well-established tunable diode laser spectroscopy of light molecules. In this paper we demonstra

It has been established, for the first time, that the shift of luminescence of Cr3+ ions in forsterite from 900 to 950 nm (FWHM~240 nm) occurs gradually as the Li-codopant concentration is increased. Selectively excited polarized luminescence at 300

In the present work iron discilicides were synthesized in tow phases: metal and semiconductor under the action of YAG:Nd+3-laser radiation on pure iron thin film to have been sputtered on Si substrate surface. Temperature dependencies of specific con

An optical communication link using a micromachined corner cube reflector (CCR) was demonstrated to transmit digital signals over a range of 2 meters by reflecting an interrogating laser from a 5mW laser source. The surface micromachined CCRs are mad

A compact programmable tuning external cavity laser has been developed using a microprocessor as the controller in which a stepper motor is employed to execute the motions of the grating for wavelength continuous tuning and a dual stage Peltier cooli

A Pulsed Short Wavelength Chemical Laser (SWCL) is essentially a bomb that produces coherent light. Current leading candidates have exothermicities ranging from 68 to 248 kcal/mol. The challenge to the fluid dynamicist is to tame the explosion and pr
