Laser effects based optimal laser parameter identifications for paint removal from metal substrate at 1064 nm: a multi-pulse model
TL;DR: In this article, the underlying mechanisms and optimal conditions for paint removal by laser ablation are thoroughly investigated on the basis of ablation morphologies and combining experiments with numerical modeling, and the authors suggest that laser paint removal is dominated by the laser vaporization effect, thermal stress effect and laser plasma effect.

Wavelength-spacing controllable, dual-wavelength synchronously mode locked Er:fiber laser oscillator based on dual-branch nonlinear polarization rotation technique.
TL;DR: To the best of the authors' knowledge, this is the first demonstration of synchronously mode locked dual-wavelength output directly from a Er:fiber laser oscillator, using dual-branch NPR technique.

Generation of wavelength- and OAM-tunable vortex beam at low threshold
TL;DR: A wavelength- and OAM-tunable vortex laser in a 1.2 W single mode fiber coupled LD pumped Yb:phosphate laser is demonstrated, which is the largest tuning range of both OAM and wavelength at ~1 W pump power range to the best of the authors' knowledge.

TL;DR: In this paper, the time dependent heat conduction equation in the laser crystal is solved numerically to predict the overall temperature rise and thermal lensing, and the thermally induced optical path difference is approximated by a quadratic distribution to obtain the focal length f of the thermal lens.

Pulsed Nd:YAP laser at 1432 nm pumped with high power laser diode
TL;DR: In this paper, the LD end-fed Nd:YAP laser operation in the eye safe spectrum region at 1432nm was reported, with pump energy of 256mJ and maximum linearly polarized output of 26mJ. The optical-to-optical overall efficiency was around 10%, and the slope efficiency was up to 18%.
