How does a pulsed laser vaporize a co target?

To introduce interior anion vacancies facilitating fast electron transport, Du et al. and Tüysüz et al. proposed the combination of LIL with chemical oxidization/reduction reactions. 182, 183 The pulsed laser (wavelength: 1064 nm; frequency: 15 Hz; energy: 700 mJ) resulted in vaporization of the Co target, producing Co vapor.

What is laser enabled material synthesis & processing?

Policies and ethics The vast field of laser-enabled material synthesis, manufacturing, and processing to a large degree relies on the ability to induce and control a range of thermal processes triggered by the laser energy deposition as well as subsequent transport processes involving...

Can a laser pulse withstand a rapid onset of melting?

This estimation suggests that, for laser pulses with sub-nanosecond pulse duration, the heterogeneous melting process would not be able to keep up with the heating rate. As a result, the material in the surface region of the target can be superheated up to the limit of crystal stability against a rapid onset of melting.

How can laser-sculpted carbide be used to generate energy?

One way to take advantage of such structures is in light capture; for example, the highly porous and curved carbide “walls” can efficiently harvest solar energy and transfer it to water for the generation of steam. Laser-sculptured carbide is sonicated in a water/ethanol mixture to detach from a glass substrate.

What determines the interaction time of a pulsed laser?

The interaction time t is typically defined by the characteristic pulse width of pulsed lasers and flash lights. For continuous-wave (CW) lasers, this is determined by the scanning speed and beam spot size . The pulse duration influences the heat diffusion length \ ( {l}_ {th}\). This relationship can be expressed as follows:

Does laser ablation cause vapor bubble expansion in a metastable liquid?

Under pulsed laser ablation of metals in vacuum, the metastable liquid may reach pressures of the order of 10 8 Pa due to the recoil vapor pressure. In Mazzi et al. (2015), the dynamics of vapor bubble expansion in a metastable liquid was described on the basis of an original method proposed by Lee and Merte (1996).
