Distributed-feedback lasing from dye-doped holographic polymer dispersed liquid crystal transmission grating
摘要
Abstract
In this paper, we report the fabrication of dye-doped holographic polymer dispersed liquid crystal (HPDLC) transmission grating and the property of distributed-feedback lasing from dye-doped HPDLC transmission grating. Under the excitation of a frequency-doubled Nd: yttrium-aluminum-garnet laser operating at a wavelength of 532 nm, optically pumped lasing with narrow linewidth and low threshold was observed from a DCM dye-doped HPDLC transmission grating with the grating period of 586 nm. The results showed that the emitted lasing peak centered at about 603 nm with a full width at half maximum ( FWHM ) of only 1.4 nm, and the threshold pumping intensity was about 17. 3 μJ, which is evidently lower than the previously reported values.关键词
