We report on the performance of a Cr/sup 4+/:YAG laser, tunable over the range from 1.32 to 1.53 mu m, under different operating conditions. Laser action has been achieved by pumping with a Nd:YAG laser in the Q-switched mode and cw mode and with a C

We have investigated the spectral and temporal dynamics associated with phonon decay in the YAG:Pr3+ system at a range of temperature between 9 and 25 K. Nonequilibrium phonons were generated using defect induced one phonon absorption (DlOPA) of far

We find that the Ce3+ ion in polycrystalline sputtered SrS:Ce thin films resides in a distorted octahedral environment, as opposed to the cubic host environment. Using electron paramagnetic resonance and x-ray diffraction analysis, we show that the d

Saturation absorption experiments are conducted on the title compound at 1.064 μm with laser light propagating along both the [001] and [111] crystallographic axes. Rotation of the crystals about these axes during the experiments reveals that the tr

Monochromatic phonons are generated in LiYF4:Pr3+ using defect induced one phonon absorption (DIOPA) of far infrared radiation. Phonons are detected in a time resolved, frequency selective manner using an absorption vibronic sideband spectrometer. Th

Defect-induced one-phonon absorption1 of far-infrared radiation is used to generate monochromatic nonequilibrium phonon populations in LaF3:Pr3+ at a range of frequencies throughout the acoustic band. The pump source for this generation mechanism is

Gallium codoping has been identified as an effective flux agent for SrS:Ce phosphor thin films. When rapid-thermal-annealed at temperatures above 750°C, the microstructure of sputtered SrS:Ce,Ga,F thin films underwent a transformation from columnar
