Removal of microsphere particles from the surface of the substrate by the directional shockwave induced by the laser pulse emitted from the “micro-gun” propulsion system tip

These dataset is the original data of paper "A modified formula of thermal focal length for lamp pumping Cr,Er:YSGG crystal with high performance 2.79 μm laser".

Under the pump power of 8.84 W, the maximum single pulse energy of 12.8 μJ and peak power of 30 W can be obtained, corresponding to the perfect pulse duration and maximum repetition rate of 427 ns and 82 kHz, respectively. It is the first presentation of such kind of WSe2-SA employed in a solid-state Q-switched crystalline laser at 2 μm, to the best of our knowledge.

Melt pool area acquired for the three different processing strategies.

Cut front & kerf profile data given as polynomial equations of the curve fit. The appended data is rotated 90 degrees counterclockwise (both Cut front & kerf profile). Because of this the Left kerf corresponds with the lower kerf and the right kerf with the upper kerf. File name explanation: 2mm_Fibre_CutFront_Equation.mat: Cut front data for Fibre laser cutting of 2 mm sheets. Data in the form of polynomial equation. 3mm_CO2_Kerf_Equation.mat: Lower (left) & Upper (right) kerf data for CO2 laser cutting of 3 mm sheets. Data in the form of polynomial equation. The following concerning cut front data; In the *.mat files, the equations are stored as Matlab cfit structures: fitobject: cfit structure for cut front polynomial equation. The following concerning the kerf profile data; In the *.mat files, the equations are stored as Matlab cfit structures: fitobjectLower: cfit structure for lower kerf polynomial equation. fitobjectUpper: cfit structure for upper kerf polynomial equation.

Cut front & kerf profile data given as x, y and z coordinates of polynomial curve fits. In *.txt files: y1 and z1 coordinates belong to the left kerf side. y2 and z2 coordinates belong to the right kerf side. The appended data is rotated 90 degrees counterclockwise (both Cut front & kerf profile). Because of this the Left kerf then corresponds with the lower kerf and right kerf with the upper kerf. File name explanation: 2mm_Fibre_CutFront_RawData.txt: Cut front data for Fibre laser cutting of 2 mm sheets. Data in the form of x and z coordinates. 3mm_CO2_Kerf_RawData.txt: Kerf data for CO2 laser cutting of 3 mm sheets. Data in the form of y and z coordinates.
