摘要：
The durability of a liquid crystal (LC) modulator for use with a high power laser is measured at a wavelength of 808 nm. It is shown that the LC modulator can withstand a laser power density of 133 W cm(-2). For a laser power density greater than 133 W cm(-2) the phase transition is caused by the absorption of the material. In order to improve the durability, the absorption of glass, polyimide (PI), indium tin oxide and LC were measured. Results indicated that the phase transition of the nematic LC is mainly caused by the absorption of glass and PI. These results can be used for a LC modulator with nematic LC material, and it is important to use an LC modulator in optical systems with high power lasers.
