MATERIAL PROCESSING DEVICE AND METHOD FOR OPERATION OF THIS DEVICE Russian patent published in 2014 - IPC A61F9/08 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A material processing laser comprises a laser generating a pulsed laser radiation beam, measuring instruments for measuring power levels of a fundamental harmonic of the laser radiation beam and a power level of at least one higher harmonic derived by multiplying a laser radiation frequency, and an evaluation unit connected to the measuring instruments and configured to evaluate the laser radiation beam quality on the basis of the measured power level of the fundamental harmonic and on the basis of the measured power level of the laser radiation. A conversion efficiency measures the wave front quality and pulse duration generating the laser radiation beam.

EFFECT: calculating a ratio of the measured level of the higher harmonic to the measured power level of the fundamental harmonic enables evaluating the current frequency conversion effectiveness.
