Femtosecond Laser Direct Writing of Flexible Electronic Devices: A Mini Review

Materials
By virtue of its narrow pulse width and high peak power, the femtosecond pulsed laser can achieve high-precision material modification, material additive or subtractive, and other forms of processing.

Effect of Femtosecond Laser Polarization on the Damage Threshold of Ta₂O₅/SiO₂ Film

Applied Sciences, 2022
The study used linearly and circularly polarized femtosecond pulsed lasers to irradiate a Ta2O5/SiO2 film. Firstly, the damage thresholds of the film for linearly and circularly polarized femtosecond pulsed lasers were measured in 1-on-1 mode.

Femtosecond laser cataract surgery [PDF]

Eye and Vision, 2015
Femtosecond laser (FSL) cataract surgery is in its infancy but is rapidly gaining popularity due to the improved consistency and predictability for corneal incisions and anterior capsulorhexis. It enables subsequently less phacoemulsification energy and time to be employed, which has gains in terms of reduced corneal oedema. In addition, the FSL allows

Femtosecond laser-assisted intrastromal MyoRing implantation for correction of irregular astigmatism after penetrating keratoplasty and high myopia

Indian Journal of Ophthalmology. Case Reports, 2021
MyoRing was implanted using a femtosecond laser to correct a high irregular corneal astigmatism after penetrating keratoplasty and high myopia. Femtosecond laser-assisted intrastromal MyoRing implantation allows to increase its sphericity, regularity and

Femtosecond laser ablation of the stapes [PDF]

Journal of Biomedical Optics, 2009
A femtosecond laser, normally used for LASIK eye surgery, is used to perforate cadaveric human stapes. The thermal side effects of bone ablation are measured with a thermocouple in an inner ear model and are found to be within acceptable limits for inner ear surgery.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
