“…6,7,13 For pinpoints induced by 351-nm (3ω) light, size and density have been shown to depend on laser parameters such as pulse length, pulse duration, pulse shape, and fluence. 4,9,10,14,15 Both pinpoint size and density have been shown to vary with pulse duration for a fixed fluence. It has been previously demonstrated that the pinpoint density as a function of fluence, ρ(φ 1 ), measured for one pulse duration (τ 1 ) may be used to estimate the damage produced as a function of fluence by a second pulse duration (τ 2 ).…”
