AbstractIn this paper, the energy of pump threshold value of DCM doped liquid crystal laser is theoretically calculated (9.2X10(-7) J). In addition, the most suitable pump light source are selected, and the corresponding pump experiment is designed. The characteristics of the laser are studied through detecting the light intensity and wavelength of the output laser. The results show that the laser wavelength can be tuned in the range of 100 nm (585 similar to 685 nm) by changing the grating period which accords with the theoretical calculation. In the meanwhile, the laser wavelength can be tuned by applying the applied electric field. What's more, the output laser strength can also be switchable, and the intensity switchable ability can reach 90. 2%. The application prospect of dye doped liquid crystal laser in the all optical network communication field is greatly expanded because of the switchable ability. However, when the electric field increases from 0 to 20 V.mu m(-1) , the line width of the laser is increased from 0.4 to 1.5 nm. The change of line width should be noted in the tunable application of dye doped laser.
