“…The thermal-penetration depth determines the distance over which heat diffuses into the target material during the laser pulse, as a result of heat conduction. Its mathematical calculation formula is: 33 where L th is the thermal-penetration depth, D represents the thermal diffusivity, τ is the laser pulse width, and k , C , and ρ denote the thermal conductivity, specific heat capacity, and density, respectively.…”

“…For further discussion, the dependence of the ablation depth on the incident laser fluence was evaluated. Generally, two different ablation regimes are distinguished in ultrashort‐pulsed LAL, characterized by a logarithmic dependence of the ablation depth on the laser fluence [76–79] . At low laser fluences, the ablation rate is determined by the optical penetration depth δ opt (see Equation ).…”

Understanding the key steps that drive the laser‐based synthesis of colloids is a prerequisite for learning how to optimize the ablation process in terms of nanoparticle output and functional design of the nanomaterials. Even though many studies focus on cavitation bubble formation using single‐pulse ablation conditions, the ablation efficiency and nanoparticle properties are typically investigated under prolonged ablation conditions with repetition rate lasers. Linking single‐pulse and multiple‐pulse ablation is difficult due to limitations induced by gas formation cross‐effects, which occur on longer timescales and depend on the target materials’ oxidation‐sensitivity. Therefore, this study investigates the ablation and cavitation bubble dynamics under nanosecond, single laser pulse conditions for six different bulk materials (Au, Ag, Cu, Fe, Ti, and Al). Also, the effective threshold fluences, ablation volumes, and penetration depths are quantified for these materials. The thermal and chemical properties of the corresponding bulk materials not only favor the formation of larger spot sizes but also lead to the highest molar ablation efficiencies for low melting materials such as aluminum. Furthermore, the concept of the cavitation bubble growth linked with the oxidation sensitivity of the ablated material is discussed. With this, evidence is provided that intensive chemical reactions occurring during the very early timescale of ablation are significantly enhanced by the bubble collapse.
