Cholesteric liquid crystal (CLC) laser has a great application prospect in medical diagnostics,light-emitting diode,display etc.,because of the microscopic size,narrow line widt,low threshold and easy to tunning.In this talk,we will report some of our recent progresses on planar CLC cell lasers,and self-assembled CLC microdroplet laser.We demonstrate a tunable CLC cell laser in form of a planar CLC texture with alignment film.The lasing wavelengh is tunable from 618 nm to 608 nm by applying a voltage.And the lasing wavelengh also could be tunable from 619 nm to 595 nm by changing the temperature of the CLC cell.We presents a novel approach to laser tuning range broadening in photosensitive CLC formulations based on a chiral azo dopant.We design and synthesize the chiral azo dopant with axially chiral 1,1’-binaphthyl group and the distinct optical properties of the azo moiety.The optical tuning range could reach 100 nm.
