Because of its vascular selectivity, the flashlamp-pumped pulsed dye laser (585 nm) is efficacious in the treatment of vascular lesions and is successfully used for the treatment of port-wine stains and haemangiomas in children. Based on the encouraging results with these cutaneous vascular disorders, the cutaneous lesions of patients with lupus erythematosus (LE) have now also been treated wit...

Experimental results on the temperature-dependent cross-plane thermal conductivity of skutterudite thin films are presented. The films examined include IrSb3, CoSb3, and Ir0.5Co0.5Sb3 single layers, and IrSb3 /CoSb3 superlattices that are grown by pulsed-laser deposition. A differential 3v method is used to measure the cross-plane thermal conductivity of these films from 80 to 300 K. The experi...

Diode pumped solid state (DPSS) Q-switched nanosecond pulsed lasers are becoming the laser of choice for a wide variety of processes in printed circuit board (PCB) manufacturing. Lasers are being used today in PCB manufacturing for via drilling, depaneling, profiling (cutting), laser direct imaging (LDI), repair, trimming, marking, skiving and other processes. The majority of these processes ar...

A very compact explosive vapor sensor is demonstrated based on a distributed feedback polymer laser pumped by a commercial InGaN light-emitting diode. The laser shows a two-stage turn on of the laser emission, for pulsed drive currents above 15.7 A. The 'double-threshold' phenomenon is attributed to the slow rise of the ∼30 ns duration LED pump pulses. The laser emits a 533 nm pulsed output bea...

We present a set of models of AGB stars with initial mass larger than 5 M⊙ as obtained with the FRANEC code. It includes model of Z=0.02 and Z=0.001, with and without mass loss.

Angioma serpiginosum (AS) is a nevoid capillary malformation developed congenitally or thereafter. The AS stops growing after puberty and may remain persistent throughout life. The pulsed dye laser (PDL) and KTP are used to treat the AS usually after several sessions. We treated a patient with AS with only one session of intense pulsed light (IPL) therapy. A 40-year-old lady with Fitzpatrick sk...

A new self-consistency condition in pulsed lasers with strong intracavity dispersion imposes dispersion modes with specific cavity-length dependent pulse rates, utilizing pulse-train self-imaging properties of a temporal Talbot effect. We give an experimental demonstration of such a laser operation, using a long fiber cavity. We also demonstrate temporal Talbot imaging of a train of short pulse...
