چکیده

A fluctuation-free mercury arc lamp for the pumping of a cw alexandrite laser is reported. Thermal insulation of a cathode of the lamp permits 4-kW fully vaporized direct-current operation. Fluctuations owing to the pool of liquid mercury in conventional lamp tubes is completely avoided. A 17-W, cw alexandrite laser pumped by the newly developed lamp is described.

Experimental Study of a Flash-lamp Pumped Passively Q-Switched Nd:YAG Laser Using Cr4+:YAG Saturable Absorber

This paper deals with the experimental results of a xenon flash-lamp pumped passively Q-switched Nd:YAG laser using Cr4+:YAG saturable absorber. The need of a laser cavity to be integrated into a time-of-flight laser range finder is of great interest as an experimental investigation of several laser resonators. Two types of laser resonator, with different lengths, have been studied: the flat-fl...

Diode laser--pumped solid-state lasers.

Diode laser-pumped solid-state lasers are efficient, compact, all solid-state sources of coherent optical radiation. Major advances in solid-state laser technology have historically been preceded by advances in pumping technology. The helical flash lamps used to pump early ruby lasers were superseded by the linear flash lamp and arc lamp now used to pump neodymium-doped yttrium-aluminum-garnet ...

Palpable Purpura: An Uncommon Side Effect of Alexandrite Laser Hair Removal

A 40-year old woman was visited at our clinic with a history of palpable purpura appearing after alexandrite laser (Apogee 5500 Alex, 15mm spot shot, 755 nm wave length, 18 j/cm2 fluence) hair removal. The skin lesions were located bilaterally on the lower extremity (Figure1). Other physical examinations were unremarkable. The patient had no history of taking medications, underlying systemic di...
