Laser processing of sapphire substrate and related applications
TL;DR: In this paper, a method of laser processing a material to form a separated part is proposed, which includes focusing a pulsed laser beam into a laser beam focal line, viewed along the beam propagation direction, directed into the material, generating an induced absorption within the material.

TW-scale mid-infrared pulses near 3.3 μm directly generated by dual-chirped optical parametric amplification
TL;DR: In this article, the authors used a dual-chirped optical parametric amplification (DC-OPA) scheme using MgO:LiNbO3 crystals to generate a 31mJ mid-infrared (MIR) pulse with a repetition rate of 10Hz near 3.3μm.

Consequences of femtosecond laser filament generation conditions in standoff laser induced breakdown spectroscopy.
TL;DR: The results show that the filament generation conditions influence the plasma properties appreciably which include the atomic and molecular emission features, persistence and plasma fundamentals (temperature and density).

TL;DR: It is shown that the full 3D time-dependent Schrödinger equation exhibits a supplementary, quasi-instantaneous defocusing contribution missing in the weak-field model of polarization, which provides an interpretation of the higher-order Kerr effect recently observed in various gases.

Plasma perspective on strong field multiphoton ionization.
TL;DR: During strong-field multiphoton ionization, a wave packet is formed each time the laser field passes its maximum value, and one important parameter which determines the strength of these effects is the rate at which the wave packet spreads in the direction perpendicular to the laser electric field.
