Abstract
It is demonstrated that strong Bragg and long-period gratings can be written using the frequency tripled output from a high repetition rate Q-switched Nd:YAG laser. The refractive index modulation induced by the pulsed near-UV light is estimated to be about 4.5x10-4, estimated both based on the periodic transmission property of long- period gratings and the reflectance of uniform Bragg gratings. Although a peak pulse intensity of the near-UV light as high as 2x107 W/cm2 has been used, no loss due to laser induced damage to the core was observed.
