Abstract
Laser therapeutic apparatus irradiates an area of cutaneous and/or subcutaneous physical injury, with a pulsed laser wave, producing healing and pain reduction. A pulsed laser beam of desired frequency is produced by reducing the output of an oscillator via a frequency multiplier which is varied in accordance with the off-nominal frequency deviation desired, if any. The rate multiplier output wave is divided down to a selected frequency and, after amplification, generates pulsed lasing energy. In accordance with varying aspects of the instant invention, a plurality of output lasing units, and optical diffusing lenses, are provided for controlled irradiation of an entire injured area. Circuitry is also provided for detecting pulsed infrared light.
