摘要：

Masks have been produced for long period fibre grating fabrication from commercial dielectric laser mirrors. The masks, which were produced by direct patterning of a photoresist using an argon laser, can withstand in excess of 200mJ/cm(2) per 15ns pulse of 248nm laser light. The use of these masks decreased exposure times by 90% and nearly doubled the attenuation (dB) of a long period grating produced by a given UV fluence compared to chrome-on-silica masks.
