Embodiment Construction
[0025] Use as figure 1 The laser cutting system shown specifically includes an ultrafast laser 1, an optical parametric amplifier 2, an energy attenuator 3, an optical shutter 4, a focusing lens 5, a moving platform 6, and a two-phase composite material 7 to be processed;
[0026] A method for cutting two-phase composite materials using ultrafast laser, the specific steps are as follows figure 2 As shown,
[0027] Step 1: Turn on the laser, adjust the position and posture of the internal components of the laser cutting system, and calculate the average value according to the wavelength required for single-pulse laser cutting of the two materials in the two-phase composite material, as the two-phase composite material laser cutting Preset wavelength
[0028] Step 2: Ensure that the optical path of the single pulse sequence laser output in the test is turned on, and can pass through the energy attenuator, light control optical shutter, and lens in sequence until the composite materi...
