Webgratings in BK7 plates. Figure 3. Two types of modified-refractive-index internal gratings fabricated by scanning planar BK7 plate using an optical stage: (a) dot structure; (b) linear structure. The linear absorption characteristics of pristine and laser-irradiated BK7 glass were evaluated and compared in the range of 1.5–4.0 eV. WebNov 16, 2024 · The material response of Borofloat, BK7, and B270 glass targets to 34 fs pulses of 800 nm central wavelength is analyzed in the 1–30 J/cm2 fluence domain. The contours of the craters change with the fluence very much the same for all three glasses up to approximately 20 J/cm2, above which the Borofloat and BK7 continue behaving …
