Laser Ablation Process for Manufacturing Submounts for Laser Diode and Laser Diode UnitsA method for manufacturing submounts for laser diodes includes the steps of providing a base configured with a ceramic carrier and a metal layer deposited upon the substrate. The method further includes using a ...
Main advantage of laser-based optics manufacturing is the high processing speed which is independent from the surface form to be processed.The laser-based optics manufacturing process is divided into three process steps each with its own goals.High Speed Laser Ablation for fast form generation with...
Following the analysis, laser ablation of a single atom doesn’t necessarily occur at the geometric centre of a laser focus when the laser pulse energy is reduced towards the SADC threshold but appears randomly in the small range, as shown in Fig. 1e. The uncertainly limit \({r}_{m}\)...
in optical microscopy. The proposed 3D micro-device comprises a modified coverslip and a micro-sphere, facilitating easy handling and integration into any existing optical microscope. To manufacture the device, two advanced femtosecond laser techniques are employed: femtosecond laser ablation and multi-...
Laser-based agglomeration of nanoparticles has been shown using gold nanoparticles fabricated via laser ablation in liquids17,18. The aggregates formed via ablation and agglomeration can be used to enhance nonlinear optical phenomena19. However, these techniques are limited in their scale due to the ...
aA method combining laser ablation cluster formation and vapor-liquid-solid (VLS) growth was developed for the synthesis of semiconductor nanowires. In this process, laser ablation was used to prepare nanometer-diameter catalyst clusters that define the size of wires produced by VLS growth. This app...

Titanium alloy is one of the hard processing materials made by the traditional manufacturing method because of the excellent mechanical strength. Ablation of titanium alloy is investigated by using a femtosecond laser which is a regenerative amplified Ti:sapphire laser with 1kHz repetition rate, 184fs...
The generation of a white light continuum using fs-laser pulses in water has proved to result in size homogenization of colloidal nanoparticles made by ablation in water142. For example, such colloidal suspensions of Au nanoparticles are stable in time against precipitation without surfactant additives...
manufacturing. Transparent hard materials remain several major technical challenges for conventional laser processing techniques due to their high hardness, great brittleness, and low optical absorption. A variety of hybrid laser processing technologies, such as laser-induced plasma-assisted ablation, laser-...
