PROCESS OF GENERATION OF COHERENT RADIATION ACROSS F CENTERS IN CRYSTAL OF LITHIUM FLUORIDE Russian patent published in 1995 - IPC

Abstract SU 1414266 A1

FIELD: quantum electronics. SUBSTANCE: in process of formation of accompanying F-aggregate centers including F1 and F2 centers transformation of centers into working F+2

centers and excitation of F+1
 centers are conducted by wide-band radiation of gaseous-discharge pump tubes. For this purpose crystal of lithium fluoride is exposed to ionizing radiation at temperature below that of mobility of anionic vacancies. Temperature is chosen within range 78-243 K. Thus crystals of lithium fluoride were exposed to γ-radiation Co60 at temperatures 78, 200 and 243 K and were subjected to effect of pulse radiation of two xenon lamps. Sufficient concentration of F+2
 centers was formed in crystal after the average of 10 pulses and after this generation across F+2
 centers arose. EFFECT: increased radiation energy by enhanced concentration of working color centers, simplification of process.
