Method of cutting bulk amorphous alloy

A method of cutting bulk amorphous alloy, comprising:

• positioning a target cutting path of the bulk amorphous alloy in an atmosphere of an inert gas;
• cutting the target cutting path using a pulsed laser controlled by a pulse signal;
• the pulse signal having a pulse period comprising a high level duration and a low level duration;
• wherein cutting comprises of heating the target cutting path above the melting temperature (Tm) within the high level duration, and then cooling the target cutting path below the glass transition temperature (Tg) by using the inert gas at a cooling rate exceeding a critical cooling rate (Rc) to avoid crystallization of the bulk amorphous alloy within the low level duration;
• and
• removing a plurality of burrs located on a cut surface produced during the cut.
