We have developed a non-contact laser–fiberoptic system for thermoluminescence dosimetry (TLD) measurements. The system is based on: (i) linear heating of a TLD sample by a CO2 laser beam; (ii) measuring the sample's temperature, using infrared the

We present wavelength- and temperature-dependent refractive index equations for 5% MgO-doped congruent PPLN and for 1% MgO-doped stoichiometric PPLN crystals valid for a wide spectral and temperature range. The dispersion equations were derived from

Publikováno v: Optical Materials. 28:147-151

The spectroscopy of AgCl x Br 1− x crystals doped with Pr 3+ ions was investigated in the mid-IR. The absorption, luminescence emission, and the kinetic parameters were measured over a broad temperature range. We calculated the important optical pa

Improving the efficiency of an optical parametric oscillator by tailoring the pump pulse shape

Autor: Eran Tal, Ady Arie, Ofer Gayer, Zachary Sacks

Publikováno v: Optics express. 18(12)

The conversion efficiency of an optical parametric oscillator is reduced by energy consumption during build-up of signal and idler intensities and due to back-conversion effects. By tailoring the pump pulse temporal shape, we are able to improve the

We derive new temperature dependent Sellmeier equations for the extra-ordinary and ordinary refractive indices of 0.5% MgO-doped stoichiometric LiTaO3 crystal. The equations are based on quasi phase-matched frequency conversion measurements, as well
