DEVICE FOR TREATMENT OF MATERIALS (PRIMARILY BIOLOGICAL) WITH LASER RADIATION (VARIANTS) Russian patent published in 1999 - IPC

FIELD: laser engineering. SUBSTANCE: device has pulse laser, facility for laser radiation delivery to material which includes optical fibre with focusing systems at input and output, positioned in succession along optical axis. Device also includes acoustic receiver and control unit, outputs of which are connected to input of laser power supply unit and to adjustment unit input. Adjustment unit outputs are connected to corresponding inputs of laser and facility of laser radiation delivery. Device also contains laser energy meters. Like acoustic receiver, laser energy meters represent through-type transducers made in form of both thin-film and combined receivers. According to variants, receiver may be positioned on one of the above-indicated elements of facility of laser radiation delivery. Outputs of thin-film receivers may be connected to control unit inputs. Device may also have unit of separate processing of signal pyroelectric and piezoelectric components. Use of given device extends laser instruments service life and enhances their reliability, as well as reduces their mass and overall dimensions. EFFECT: enhanced efficiency. 6 cl, 11 dwg
