Microhole-pair hollow core fiber Fabry–Perot interferometer micromachining by a femtosecond laser
Sensors and Actuators A: Physical
February 2020
This study presents a sensitive and high-response microhole-pair (MP) hollow-core fiber (HCF) Fabry–Perot (FP) interferometer (MPHCFFPI) by microdrilling two holes symmetrically on the sidewall of the HCF via a femtosecond laser micromachining technique.

Real-time spectral response guided smart femtosecond laser bone drilling
Optics and Lasers in Engineering
Bone drilling is a common surgical procedure of knee arthroplasty, craniotomy, stapedotomy, dental treatment, and laminotomy. Although femtosecond laser processing provides a promising method for precision bone drilling, it is still challenging to achieve thermal accumulation suppression and damage protection for large-scale hole drilling.

Femtosecond laser surface irradiation of silicon in air: Pulse repetition rate influence on crater features and surface texture
Optics & Laser Technology
June 2020
The influence of the pulse repetition rate on laser irradiation of silicon, in air, with femtosecond laser pulses is experimentally investigated in the range 10 Hz – 200 kHz. The features of the produced crater and the laser-induced periodic surface structures generated on its surface are characterized by exploiting surface profilometry and scanning electron microscopy.
