A 60-[mu]m-thick and 0.5-mm-long LiNdPO slab waveguide laser clad by sputtered SK12 glass was fabricated. Single TE-mode pulse and quasi-cw laser oscillations at 1.047 [mu]m were obtained by longitudinal pumping with a rhodamine 6G laser and an argon laser, respectively. The round-trip waveguide los ...

A large number of laser transitions in the 1117-[mu]m region have been obtained by optically pumping CF, NOCl, CFI, and NH with a single line-tunable CO TEA laser. These lasers have respectable conversion efficiency and can be scaled to high energies in a spectral region where the selective excitati ... [J. Appl. Phys. 49, 61 (2008)] published Tue Aug 12, 2008.

Assignments are given for the 13 HCN and 4 HCN laser transitions that have not yet been identified. Although 10 different vibrational systems give rise to 27 laser transitions for HCN and HCN combined, all follow the same basic pattern involving a particular Coriolis interaction and a population inv ...

Liquid-phase epitaxial (LPE) single and multiple thin quaternary layer InGaPAs laser diodes (x~0.13, z~0.28; lambda~1.1 [mu]m, 77 degrees K) that exhibit quantum size effects (QSE) are described. LPE quaternary active layers approaching L~200 A have been achieved. As a prototype for the behavior of ... [J. Appl. Phys. 49, 69 (2008)] published Tue Aug 12, 2008.

The limitations of high-power electrical lasers due to heating of the gas and the instability of the glow discharge can be alleviated by the flow of the lasing medium. We describe here the results of two experiments which combine glow discharges with gas flow. In the first experiment we study the ef ... [J. Appl. Phys. 49, 81 (2008)] published Tue Aug 12, 2008.

Epitaxial NaCoO thin films were fabricated by the sodium deintercalation of the epitaxial NaCoO thin films in the solution of iodine-dissolved acetonitrile, in which the epitaxial NaCoO thin films were deposited on (001) sapphire substrates by pulsed laser deposition. The NaCoO thin films show small ... [J. Appl. Phys. 104, 033538 (2008)] published Wed Aug 13, 2008.

The results of coupled thermo-optical modeling of Tm,Ho solid-state laser operation are reported. A rate dynamics model integrated together with a TEM distribution for the total number of stimulated photons is coupled with a two-dimensional time-dependent heat transfer model. The heat transfer model ... [J. Appl. Phys. 104, 033114 (2008)] published Tue Aug 12, 2008.

We report the use of zone plate optics as a monochromator for the spectral selection of a single high-order harmonic of a femtosecond laser generated in a rare gas medium. We show that this is a convenient way of monochromatizing the vacuum ultraviolet (VUV) pulses in the photon energy range from 30 ... [J. Appl. Phys. 104, 033112 (2008)] published Tue Aug 12, 2008.

We examine the possibility of stimulated emission of a surface plasma wave (SPW) on a metal-vacuum interface by electron-hole recombination in a forward biased p-n junction located near the interface. We consider a thin layer of n-type semiconductor sandwiched between a metal and a p-type semiconduc ... [J. Appl. Phys. 104, 033306 (2008)] published Tue Aug 12, 2008.

Titanium oxide thin films were prepared by pulsed-laser deposition on LaAlO single crystal substrate at 700 degrees C. Pure anatase films are obtained at high oxygen pressure (10 mbar), while the rutile phase is evidenced at low oxygen pressure (10 mbar) despite a large oxygen deficiency (O/Ti=1. ... [J. Appl.
