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.

Laser therapeutic device

Improved circuitry for detecting pulsed infrared light which is particularly suitable for use with laser therapeutic devices. Laser therapeutic devices generally utilize pulsed laser energy of infrared wavelengths. Because such light is invisible the operator of the therapeutic device cannot determine if it is actually working. The invention provides pulsed infrared light detection circuitry which is very compact so that it may be made part of the therapeutic device. The circuitry includes an infrared sensitive transducer coupled to the input of an inverting operational amplifier, a peak detector coupled to the output of the inverting amplifier, and a non-inverting amplifier coupled to the output of the peak detector for driving a display to indicate the detection of pulsed infrared energy.
