:the output can be dramatically improved by isolating the dye cell thermally from the flashlamp and ensuring uniform axially symmetric flow of the dye throughout the cell. A quadraxial laser tube in which the dye cell is surrounded by an evacuated annulus to provide thermal isolation and is terminated by specially designed end caps to provide uniform injection and removal of the dye solution wa...

Divided-pulse amplification (DPA) has proven to be a valuable tool in scaling the peak power of diode-pumped ytterbium-doped amplifiers to beyond the single-pulse threshold for parasitic nonlinear effects. DPA enables the amplification of picosecond pulses in solid-state amplifiers with limited bandwidth beyond the single-pulse damage threshold. In this Letter, we demonstrate DPA of picosecond ...

The port-wine stain is a disfiguring vascular birthmark that commonly occurs on the face. Amelioration of this condition in children was difficult or impossible until the introduction of the flashlamp-pumped pulsed dye laser in the late 1980s. This article provides an interdisciplinary social and ethical examination of pulsed dye laser therapy for port-wine stain in childhood. Specific issues r...

OBJECTIVE To examine the clinical, histological, and immunohistological effects of flashlamp photoepilation. DESIGN Nonrandomized control trial with blinded histological study and follow-up of 1 to 20 months. SETTING Private academic practice. SUBJECTS Sixty-seven subjects (10 males and 57 females) with areas of excess body hair. INTERVENTIONS Single (9 subjects) or multiple (58 subject...
