Claim 0:
1. A drilling device with a controllable femtosecond laser processing taper, comprising a femtosecond laser and a precision motion table; wherein,
a support mechanism is provided along a central axis of the precision motion table, and a clamp is provided on a top of the support mechanism;
an output end of the femtosecond laser is provided with a beam expander; an output end of the beam expander is provided with a reflection mirror;
an output end of the reflection mirror is provided with a beam scanning module;
an output end of the beam scanning module is provided with a semi-focusing mirror;
an output end of the semi-focusing mirror is provided with a semi-transmissive reflection mirror arranged at 45 degrees;
a reflection output end of the semi-transmissive reflection mirror is provided with a high-precision three-dimensional on-line monitoring module, and
a transmission output end of the semi-transmissive reflection mirror faces the clamp on the precision motion table,
wherein the beam scanning module comprises a displacement optical wedge group and a deflection optical wedge group;
wherein, the displacement optical wedge group comprises a first displacement optical wedge and a second displacement optical wedge, and the first displacement optical wedge and the second displacement optical wedge have an identical wedge angle and are linked through an vertical linear motion mechanism;
wherein, the deflection optical wedge group comprises a first deflection optical wedge and a second deflection optical wedge, and the first deflection optical wedge and the second deflection optical wedge have an identical wedge angle and are equidistantly distributed on both sides of the displacement optical wedge group through a rotating mechanism.
