Cr:LiSrAlF6 crystals area a very interesting laser medium due to its spectroscopic characteristics, presenting a broad emission band in the near infrared and being able to be pumped either by flashlamp or by diodes. Up to now, its limitation is mostly due to its poor thermal properties that limit the laser performance either in the repetition rate in pulsed system or output power in CW systems....

The pulse-burst duration of a compact burst-mode Nd:YAG laser is extended by one order of magnitude compared to previous flashlamp-pumped designs by incorporating a fiber oscillator and diode-pumped solid-state amplifiers. The laser has a linewidth of <2 GHz at 1064.3 nm with 150 mJ per individual pulse at 10 kHz. The performance of the system is evaluated by using the third-harmonic output at ...

OBJECTIVE To study the effect of laser treatment on rosacea, a common facial skin disease with symptoms of blushing, redness, telangiectasis, papules, pustules, and diffuse swelling of the skin, we focused on the stinging sensation and performed immunohistochemical evaluation of nerve density and neuropeptide expression. DESIGN Clinical investigation as well as the lactic acid (stinger) test ...

The optical pumping of laser-induced copper plasma by incoherent light a fast-discharge xenon flashlamp is proposed to enhance the stimulated emission (LIP). To study spatiotemporal evolution LIP, numerical approach based on collisional-radiative model and kinetic equations has been employed. influence total density gas temperature gain coefficient plume was studied. results show an enhancement...

A new, high-repetition-rate pulse-burst laser system for the MST Thomson scattering diagnostic has operated with 2 J pulses at repetition rates up to 75 kHz within a burst. The 1064 nm laser currently employs a q-switched, diode pumped Nd:YVO4 master oscillator, four Nd:YAG amplifier stages, and a Nd:glass amplifier, with plans for an additional Nd:glass amplifier. The laser can maintain 1.5–2 ...

The treatment of port wine stains (PWSs) using a flashlamp-pumped pulsed dye laser is often performed using virtually identical irradiation parameters. Although encouraging clinical results have been reported, we propose that lasers will only reach their full potential provided treatment parameters match individual PWS anatomy and physiology. The purpose of this paper is to review the progress ...
