Considering the practical applications of liquid-crystal microlasers, such as laser displays and opto-communication devices, broadband tunablity and continuous wave (cw) operation are strongly desired. Especially for the later one, nobody has succeeded yet. For the cw operation, two problems must be solved: (1) Development of new dyes which are stable against heat and light; (2) Development of novel cavities with high Q which makes the lasing threshold lower. Here in this paper, we will introduce our recent researches mainly aiming at reduction of the lasing threshold in liquid crystal microlasers; (1) single-output window devices; (2) multilayered devices; (3) use of a polymer dye improving order parameter; (4) a new laser dye specially designed for dye-doped CLC lasers.
