WebNov 22, 2024 · A short-pulse-width repetitively Q-switched 2.7-μm Er:Y2O3 ceramic laser is demonstrated using a specially designed mechanical switch, a metal plate carved with slits of both slit-width and duty-cycle optimized. With a 20% transmission output coupler, stable pulse trains with durations (full-width at half-maximum, FWHM) of 27–38 ns were …
Laser ablation of CFRP using picosecond laser pulses at different ...
WebOct 14, 2024 · TOKYO, October 14, 2024 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it will launch on October 18 two new CV Series models of 3D CO 2 laser processing systems for cutting carbon fiber reinforced plastics (CFRP), which are lightweight, high strength materials used in automobiles. WebOne of the major reasons for the formation of a heat-affected zone during laser processing of carbon fiber-reinforced plastics (CFRP) with repetitive picosecond (ps) laser pulses is heat accumulation. A fraction of every laser pulse is left as what we termed residual heat in the material also after the completed ablation process and leads to a gradual … check engine light 2001 jeep wrangler
