Ineffective treatment of refractory melasma and postinflammatory hyperpigmentation by Q-switched ruby laser.

The Journal of Dermatologic Surgery and Oncology, 1994
BACKGROUND Melasma and postinflammatory pigmentation are cosmetic problems with limited options for treatment. OBJECTIVE To determine whether selective photothermolysis of pigmented cells by Q-switched ruby laser treatment would produce clinical ...

Benign pigmented lesions of the skin. Treatment with the Q-switched ruby laser.

The Journal of Dermatologic Surgery and Oncology, 1993
BACKGROUND The Q-switched ruby laser is a 694 nanometer (red light) pulsed (20-40 nsecond) laser that has been shown to be effective in the treatment of cutaneous pigmented lesions.

Ruby laser damage and pigmentation of the iris

Experimental Eye Research, 1969
The analysis of damage to the rabbit iris following laser irradiation has been continued with an investigation of its effects on protein synthesis as measured by autoradiographic grain-counting, and on an enzyme system (DPN diaphorase). Enzyme studies were also performed on monkeys and guinea pigs and the histopathology of lesions in the latter species

THE RUBY LASER: PUMPED BY A PULSED ARGON ION LASER

Applied Physics Letters, 1968
A ruby laser with a pulsed argon ion laser as a pump was constructed and operated at 77° and 300°K. Threshold for oscillation was ∼13 mJ. A unique type of Q-switched operation was observed that produced pulses of ∼15 nsec at 300°K and ∼6 nsec at 77°K.

Fluorescence of Ruby Laser Rods

Applied Spectroscopy, 1987
Fluorescence studies of the R-line emission of ruby laser rods over the temperature range of 77 to 300 K have disclosed several new features. In particular, for most of the ruby rods, the fluorescent decay time, τ, was not strictly exponential. Effects of this kind have been observed in the fluorescent decay of the 4F3/2 level of Nd3+ in YAG (yttrium ...
