How laser is generated
Web19 jan. 2024 · Herein a laser beam is focused using a plano-convex lens to elevate the laser fluence above the threshold for LA, which is 10 12 –10 14 W/m 2 (Torrisi et al., 2007; Kajiwara and Hosoya, 2011; Hosoya et al., 2012, 2016a, 2016c, 2016d), and irradiated onto the LA generation point of the target structure. Web18 nov. 2024 · However, lasers do not occur naturally and are generated by stimulating a light source such as a semiconductor diode, ruby crystal, CO2 gas, etc. The light generated by the source is then amplified and converged towards a point to eliminate or minimize the loss of energy by dispersion.
