Claim 5:
6. A drilling process with the controllable femtosecond laser processing taper based on the drilling device of claim 1, comprising:
activating the femtosecond laser to emit a beam;
expanding the beam through the beam expander to reach a required diameter for processing, wherein the beam enters the reflection mirror;
reflecting the beam to the beam scanning module through the reflection mirror to generate a spiral beam under an action of a displacement optical wedge group and a deflection optical wedge group, wherein the spiral beam enters a semi-transmissive reflection mirror through a semi-focusing mirror to generate a reflected beam, and the reflected beam enters the high-precision three-dimensional on-line monitoring module under an action of the semi-transmissive reflection mirror;
using the reflected beam transmitted through the semi-transmissive reflection mirror to perform laser drilling for a sample fixed on the clamp;
performing detection in real time through the high-precision three-dimensional on-line monitoring module; and
adjusting an error generated in a processing procedure to improve a processing precision,
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.
