摘要:

We report about a nematic liquid crystal device suitable for efficient coherent beam amplification. A proposed novel hybrid structure is composed of nematic liquid crystal layer sandwiched between suitable ultra thin photoconducting (Disperse Red 1 functionalized polythiophene) polymeric surface layers serving as orienting as well as space charge generating layers upon light incidence. The gain coefficient measured at incidence angle 45∠ in 10 μm thick liquid crystal layer in a conventional two-wave mixing experiment is one of the highest reported so far for the similar systems and amounts tog= 7. The net exponential gain coefficient is very high Γ 2600 cm−1and is obtained at voltages below 1 V/μm.
