PROCESS OF MANUFACTURE OF ACTIVE LASER MEDIUM ON BASE OF MONOCRYSTAL OF LITHIUM FLUORIDE WITH F₂ CENTERS

摘要

FIELD: quantum electronics. SUBSTANCE: crystal of lithium fluoride is irradiated with heavy-current electron pulses with 10 ns duration. Energy of electrons is established at 200 keV and current in beam is set at F₂. Irradiation is performed at room temperature. For the course of 50 s crystal is irradiated with 300 pulses. Used irradiation value is equal to 0.8, where , is time of life of anionic vacancies. Experiments display necessity of selection of irradiation time from 0.1 up to 65 to increase stability of concentration of t centers. EFFECT: increased stability of concentration of F₂ centers.
