Treatment of small and medium congenital nevi with the Q-switched ruby laser.
Archives of Dermatology, 1996BACKGROUND The Q-switched ruby laser has been used successfully to treat a variety of benign pigmented lesions. In this study, congenital nevi (diameter, < or = 5 cm) in 18 prepubertal children were treated with the Q-switched ruby laser.

The Q-switched Ruby Laser in Glaucoma
Ophthalmology, 1984A pilot study evaluated the safety and effectiveness of a Q-switched ruby laser in the treatment of both pupillary-block (10 eyes) and open-angle glaucoma (4 eyes). All patients had either poor visual acuity or had previously failed with conventional surgery. We created a patent iridotomy in all eyes, with one pulse in eight.

Losses in a Pulsed Ruby Laser*
Journal of the Optical Society of America, 1963The total cavity loss in several ruby lasers has been determined experimentally from a set of threshold measurements. Scattering loss and end-mirror reflectance were measured separately and the difference between these losses and the total attributed to diffraction. Both plane-parallel and confocal resonators were employed.

Normal-mode ruby laser for treating congenital nevi.
Archives of Dermatology, 1997BACKGROUND Q-switched laser therapy is known to be highly effective in treating dermal melanocytosis and pigmented epidermal lesions. However, to our knowledge, there are no reports on the effectiveness of laser therapy for congenital nevi.

Immersion Liquids for Ruby Lasers
Applied Optics, 1965A search was made for high index of refraction liquids suitable for immersion of ruby crystals in high-energy lasers. One liquid, SnCl2 ยท 2H2O in glycerin, is reported which can exactly match the index of ruby (1.76) and which, at the same time, is stable to the flash-lamp environment and transparent at the ruby pumping and lasing wavelengths.

Q-switched ruby laser treatment of nevus of Ota.
The Journal of Dermatologic Surgery and Oncology, 1992Emission of 694-nm laser energy from a Q-switched ruby laser causes photodestruction of cutaneous pigment. The 40-nanosecond pulse duration of Q-switched ruby laser light initiates specific damage to melanosomes thus allowing selective treatment of ...

Q-switched ruby laser therapy of nevus of Ota.
Archives of Dermatology, 1992BACKGROUND The Q-switched ruby laser has been demonstrated to provide selective photothermolysis of pigmented tissue at a wavelength of 694 nm and a pulse width of 40 ns with dermal penetration.

Treatment of tattoos by Q-switched ruby laser. A dose-response study.
Archives of Dermatology, 1990Tattoo treatment with Q-switched ruby laser pulses (694 nm, 40 to 80 nanoseconds) was studied by clinical assessment and light and electron microscopy.
