Pd<SUB>77</SUB>Cu<SUB>6</SUB>Si<SUB>17</SUB> thin film metallic glasses of which thicknesses were 10, 20 and 28 µm were bent by laser forming. The working conditions were changed and crystallization of thin films was investigated. When the laser power was changed under fixing the scanning velocity to 40 mm/s and the Q-switch frequency to 3 kHz, crystallization was observed at laser irradiated surface and/or the reverse side to the laser irradiation. In a case of changing the scanning velocity under fixing the Q-switch frequency to 3 kHz and the laser power to 2.0 W for the film thickness of 20 µm and 3.0 W for the film thickness of 28 µm, the working conditions without crystallization were found at high scanning velocity. When the Q-switch frequency was changed under fixing the scanning velocity to 40 mm/s and the laser power to 2.0 W for the film thickness of 20 µm and 3.0 W for the film thickness of 28 µm, the working conditions without crystallization were found at low Q-switch frequency.
