Excimer laser ablation of gold films deposited on a quartz crystal microbalance is investigated. The ablation rate is directly obtained from the frequency shift of the microbalance. The measured single-shot ablation rate is found to be at least two orders of magnitude higher than the numerical predictions based on a surface vaporization model. Surface morphologystudies indicate that hydrodynami...

Vibrationally resolved electronic spectra are reported for the diatomic cations Tel and Bi: using the technique of resonance-enhanced photodissociation spectroscopy (REPD). These ions are generated by laser vaporization in a pulsed nozzle source, jet-cooled, mass-selected with a reflectron time-of-flight spectrometer, and dissociated on resonance with a tunable dye laser. Electronic excitation ...

A. Alpha adrenergic blockers (alfuzosin, doxazosin, silodosin, tamsulosin, and terazosin) B. Hormonal manipulation (including finasteride, dutasteride, and dutasteride plus tamsulosin) C. Interstitial laser coagulation of the prostate (ILCP) D. Laser prostatectomy E. Laser based procedures including contact laser ablation of the prostate (CLAP), holmium laser procedures of the prostate (HoLAP, ...

Heat conduction after the application of a short laser pulse on opaque matter is calculated assuming simplifying conditions. The effect of the simplifications on real systems is discussed. It is found that Fourier’s law may reasonably be applied considerably above the temperature of vaporization of the substrate. Calculated and experimental ablation at nickel surfaces using fluences below thres...

Disseminated superficial actinic porokeratosis (DSAP) is a skin condition that usually shows a poor response to different modalities of treatment. Herein we describe 2 patients with DSAP on the face, each treated with 3 to 4 sessions of photodynamic therapy combined with laser vaporization.

Winkler's disease otherwise known as chondrodermatitis nodularis chronica helices (CNHC) is characterized by a painful persistent erythematous nodule, mostly located at the rim of helix of pinna. Occurs mostly in men over 40 years of age. Standard therapy is by local excision or carbon dioxide laser vaporization. Recurrence is frequent.

Gas phase ion mobility measurements can resolve structural isomers for polyatomic ions and provide information about their geometries. A new experimental apparatus for performing high-resolution ion mobility measurements is described. The apparatus consists of a pulsed laser vaporization/desorption source coupled through an ion gate to a 63-cm-long drift tube. The ion gate is a critical compone...
