The present case report was a 36-year female with lesion on the right side of inner lower lip and diagnosed as pyogenic granuloma occurring at an unusual site. presently available treatment for is surgical excision which might delay wound healing due to complications such intraoperative bleeding post operative infection. Other modalities cryosurgery, CO2 Nd:YAG lasers, flash lamp pulsed dye abl...

We have used the Doppler-free, perturbation-facilitated optical-optical double-resonance technique to investigate the vibrational, rotational, and hyperfine structure of the 3 (3)Pi double minimum state of NaK. Since this electronic state arises from an avoided crossing with the nearby 4 (3)Pi state, we observe striking patterns in the data that provide a sensitive probe of the electronic wave ...

We report the demonstration of compact fluidic fibre lasers based on capillary tubes and photonic crystal fibres, featuring single channel and multiple laterally integrated fluidic lasers respectively. Their preparation was based on capillary action and lasing occurred without the need for external mirrors or lithographically defined microstructures. The fibre lasers were found to be tunable by...

Organic dye-doped polymers have been widely investigated as gain media in solid-state dye lasers. Dye molecules which have large absorption and induced emission cross sections due to allowed π-π transitions are ideal active dopants for the generation and amplification of intense light pulses. However, continuous wave operation is not feasible with organic dyes because of the triplet losses. On ...

BACKGROUND The pulsed dye laser (PDL) has long been used for treatment of erythematous and hypertrophic scars. Its effectiveness has been attributed in large part to its vascular-specificity. The vascular-specific potassium titanyl phosphate (KTP) laser has also been reported to be clinically effective for scars, but has not been compared to the PDL. OBJECTIVE To compare the safety and clinic...

BACKGROUND The S-Caine peel (Zars, Inc., Salt Lake City, UT) is a novel eutectic lidocaine/tetracaine mixture that is applied as a cream, drying upon exposure to air to form a flexible film that can be peeled off easily. The patented formulation can be used to anesthetize the skin prior to a variety of cutaneous procedures. OBJECTIVE To examine the clinical efficacy of the S-Caine peel as a t...

A tunable ArF* (193-nm) excimer source is described that produces over 125 mJ/pulse (peak) at 10 pulses/sec. This device has a spectral width of less than 2 cm(-1) and a demonstrated tunability of nearly 320 cm(-1) from 192.8 to 193.9 nm. Tunability, bandwidth, and mode control are achieved by injecting the fourth anti-Stokes line (in H(2)) of a frequency-doubled dye laser into an ArF* excimer-...
