Q-switched ruby laser treatment of tattoos and benign pigmented skin lesions: a critical review.
Annals of Plastic Surgery, 1998The Q-switched ruby laser (694 nm, 25-40 nsec) is an effective and safe therapeutic device for the treatment of tattoos and well-defined, benign, pigmented epidermal and dermal lesions.

Temperature field of a ruby laser
Journal of Applied Spectroscopy, 1966Formulas describing the temperature fields of a ruby laser cooled in various ways are derived. The laser can operate either as a single pulse generator or as a source emitting free-generation pulses at a specified frequency. The resulting formulas are used to compute the heating and cooling of the active medium of the ruby laser.

Characteristics of an argon−laser−pumped ruby laser
Journal of Applied Physics, 1975The characteristics of a quasi−cw single−mode ruby laser which is pumped by an argon laser are described. Particular emphasis is given to aspects which govern the linewidth. By heterodyning two independent lasers, linewidths as narrow as 0.5 MHz have been observed, averaged over a few seconds.

BACKGROUND The Q-switched ruby laser (QSRL) (694 nm) has been used successfully in the removal of tattoos and a variety of cutaneous pigmented lesions. The frequency-doubled Q-switched neodymium:yttrium-aluminum-garnet laser (QSNd:YAG) (1064 and 532 nm ...

Q-Switched ruby laser therapy of acquired bilateral nevus of Ota-like macules.
Dermatologic Surgery, 1999BACKGROUND Acquired bilateral nevus of Ota-like macules (ABNLM), also called nevus fuscoceruleus zygomaticus or nevus of Hori, is a relatively common disease in Asia. It is refractory to all medical treatment.

Regenerative Ruby Laser Amplifiers
Journal of the Optical Society of America, 1966An ideal laser amplifier was previously treated as a three-medium transmission system. It was predicted that for a given length, the gain would rise with negative attenuation (population inversion), reach a maximum, decrease rapidly at first, and then gradually approach zero asymptotically.The theory has been tested experimentally, using ruby at liquid-

Q-switched ruby laser pulses cause selective damage to cutaneous pigmented cells. Repair of this selective damage has not been well described. Therefore, using epilated pigmented and albino guinea pig skin, we studied the acute injury and tissue repair ...

An analysis is performed for a pulsed ruby laser with a modulator internal to the interferometer resonator. The problem is a transient one, since steady state is not reached during the period of oscillation of the pulsed laser. The solution obtained is not a steady-state solution, but is applicable to the time interval of interest for the ruby laser ...
