FIELD: radio engineering.
SUBSTANCE: quartz crystal resonator contains vacuum-treated housing with internal heat-reflective coating inside of which there is heater - laser diode fixed in the center at radiator in a form of metal disk plate that is held by metal rods, lensed quartz piezoelectric element, focusing lens, note that metal disk plate on which there attached is a laser diode is done in a form of disk with slots of rectangular form forming lamels starting from the place of laser diode attachment, formed lamels are attached by metal rods going through dielectric isolators of metal support ring, note that the surface of metal lamels at the laser diode attachment foundation is covered by cylindrical beads from porous gas-absorbing titanium that releases necessary gas volume, for example helium, at forced heating of quartz crystal resonator and the said gas is absorbed till rarefication 10-6 in quartz crystal resonator volume in operating condition.
EFFECT: reduction of temperature-dynamic coefficient of quartz crystal resonator, reduction of available time.
