Saturation characteristics of CHOCH and CClF were investigated in the intensity range 10 to 5 x 10 W/cm using a nanosecond CO laser. The ratio of the low-intensity absorption cross section to high-intensity absorption cross section ranges between 3 and 6 for the CO 10.6-[mu]m P (22) laser line, indi ... [Appl. Phys. Lett. 32, 38 (2008)] published Fri Aug 8, 2008.

A dye laser controlled semiconductor reflection switch has been used to gate subnanosecond pulses of 10.6-[mu]m radiation from the output of a ~1-W cw CO laser. Upon injection into a multiatmosphere CO oscillator, high-power mode-locked pulses having a duration <~200 ps and a peak single pulse energ ... [Appl. Phys. Lett. 32, 27 (2008)] published Fri Aug 8, 2008.

Gain-switched CO laser pulses of 225 J were focused onto planar carbon targets in the presence of longitudinal magnetic fields up to 105 kG. For fields above 25 kG, the mass loss and cross-sectional area of the cylindrical blow-off plasma varied as B. For these cases, only the 60-nsec gain-switched ... [Appl. Phys. Lett. 32, 10 (2008)] published Fri Aug 8, 2008.

Thick films of 0.7BiFeO0.3PbTiO have been deposited on sapphire substrates by tape casting and sintering at 1000 degrees C. Films 20 [mu]m in thickness were released from the fabrication substrate using KrF pulsed laser radiation, and epoxy bonded to platinized silicon substrates in order to demo ... [Appl. Phys. Lett. 93, 052909 (2008)] published Thu Aug 7, 2008.

PH, AsH, and BH have been removed from SiH by means of selective photolysis with an ArF uv laser. The absolute absorption cross sections for SiH, PH, AsH, and BH have been determined over the region 190200 nm. Quantum yields for destruction of the contaminant species have been measured at 193 nm. Th ... [Appl. Phys. Lett. 32, 46 (2008)] published Fri Aug 8, 2008.

A zigzag quasilongitudinally (theta=15 degrees ) CO laser-pumped DO oscillator at 66 [mu] is described. Maximum energy was 42 mJ in a 2.5-[mu]s pulse, representing ~9% quantum conversion efficiency. The spectrum was only a few axial modes wide. With a single-pass mirrorless arrangement, a strong sup ... [Appl. Phys. Lett. 32, 44 (2008)] published Fri Aug 8, 2008.

The performance of a high-repetition-rate (kHz) Raman oscillator is described. The oscillator employs a new configuration in which the Raman medium is located inside the pumping laser, and the Stokes outputs and pumping laser share the same resonator. The Raman oscillator consists of lithium iodate ... [Appl. Phys. Lett. 32, 52 (2008)] published Fri Aug 8, 2008.

The full hyperfine components of the R (127) line in the 11-5 band and the 10 components of the P (33) line in the 6-3 band of the B<--X electronic transition of I were observed by the saturated absorption spectroscopy using a complex resonator He-Ne laser. The frequency of the laser was locked to e ... [Appl. Phys. Lett. 32, 114 (2008)] published Fri Aug 8, 2008.

The results obtained from a comprehensive theoretical model for an electrically excited laser are compared with experimental data obtained from a large-volume KrF laser device, excited by an e-beam only, or with enhancement from an electric discharge. ...

Tunable subpicosecond pulses (pulse width =0.8 psec) have been obtained from a cw mode-locked Rhodamine B dye laser. Mode locking is achieved by synchronous pumping of the Rh-B dye with a cw train of pulses which are obtained from a synchronously mode-locked Rhodamine 6G dye laser. ... [Appl. Phys.
