Ultrafast and precision drilling of glass by selective absorption of fiber-laser pulse into femtosecond-laser-induced filament

, 2018
The extremely intense light emitted from femtosecond laser pulses enables micro-drilling of glass. However, there are problems in femtosecond laser drilling, including low drilling speed and the damage during drilling.

Femtosecond laser ruler

Quantum Electronics, 2008
A new method for identifying interferometer pass bands used as marks on the femtosecond meter scale is proposed and realised. The possibility of creating a femtosecond laser ruler is demonstrated experimentally.

Nanosurgery with Femtosecond Lasers

Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009
Femtosecond laser pulses make it possible to ablate cell structures at the submicrometer scale. We apply this technique to study biological processes in living cells and to help identify the function of neurons in nematodes.

Direct writing of plane-by-plane tilted fiber Bragg gratings using a femtosecond laser.

Optics Letters, 2017
In this Letter, we report a flexible, plane-by-plane direct write inscription method for the development of tailored, tilted fiber Bragg gratings using a femtosecond laser. Compared to ultraviolet or femtosecond laser inscription based on the phase mask,

Femtosecond Laser Micromachining [PDF]

, 2013
Ultrashort laser pulses with durations in the femtosecond range up to a few picoseconds provide a unique method for the structuring of practically all materials with high precision and minimal thermal and mechanical influence of the surrounding. Due to the high intensities obtained in the focal volume even at moderate pulse energies not only surface ...

Femtosecond Laser Fundamentals

2012
When reading about a new medical technology, such as femtosecond (FS) lasers for eye surgery, the average clinician is stepping into an unfamiliar world of laser physics and engineering terms that can easily overwhelm his understanding. It may be easy enough to conceptualize how a laser can focus into the lens or cornea in order to achieve a ...
