Femtosecond Laser Ablation of Sapphire
INSTRUCTION Sapphire is widely used in the field of optical components and micromechanical devices owing to its useful mechanical, optical, and electrical properties. However, sapphire is mechanically and chemically difficult to machine because of its high hardness and chemical stability. The difficulty of machining sapphire has restricted the development of advanced device structures. As sapph...
متن کاملFemtosecond laser near field ablation
The hi gh fi eld strength of fe mtosecond laser pulses leads to non I incar effects during the interacti on with condensed matter. One such e ffect is the ab latio n process, which can be initiated he low the threshold of common thermal ahlation if the excitation pul ses are suffic iently short . This effec t leads to structure formation, which is an isotropic because of the polari zation prope...
متن کاملFemtosecond Laser Ablation: Fundamentals and Applications
Traditionally nanosecond laser pulses have been used for Laser-induced Breakdown Spectroscopy (LIBS) for quantitative and qualitative analysis of the samples. Laser produced plasmas using nanosecond laser pulses have been studied extensively since 1960s. With the advent of short and ultrashort laser pulses, there has been a growing interest in the applications of femtosecond and picosecond lase...
متن کاملBasic Physics of Femtosecond Laser Ablation
Laser ablation being the basic process for many prominent applications of lasers in present day high technology, medicine, and other fields, its basic physics is reviewed in this chapter. In order to distinguish the fundamental, laser–material interaction from any secondary effects, we concentrate on ultrashort laser pulses (≈100 fs duration) at comparably low intensities, below the commonly in...
متن کاملSimulation of femtosecond laser ablation of silicon
Femtosecond laser ablation is an important process in the micromachining and nanomachining of microelectronic, optoelectronic, biophotonic and MEMS components. The process of laser ablation of silicon is being studied on an atomic level using molecular dynamics (MD) simulations. We investigate ablation thresholds for Gaussian laser pulses of 800 nm wavelength, in the range of a few hundred femt...
