Beschreibung
Zusammenfassung:	FIELD: radio electronics. ^ SUBSTANCE: piezoid is exposed to focused pulse radiation of laser beyond disposition region of electrodes at Q-factor modulation with energy density in laser beam constriction exceeding laser destruction threshold of crystal piezoid to produce microscopic destruction therein measuring 30 to 100 mum. Impact points are chosen at distance L = (3t + 0.5) mm from piezoid electrode edge, where t is piezoid thickness in millimeters. Laser radiation energy density is below laser destruction threshold of resonator glass package residing beyond laser beam constriction region. ^ EFFECT: improved monotony of glass-packaged crystal resonator temperature and frequency characteristics with basic parameters retained. ^ 1 cl, 1 dwg
