Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

open access: yesAdvanced Materials, EarlyView.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Picosecond high-repetition-rate pulsed laser ablation of dielectrics: the effect of energy accumulation between pulses [PDF]

open access: yes, 2015
We report experiments on the ablation of arsenic trisulphide and silicon using high-repetition-rate (megahertz) trains of picosecond pulses. In the case of arsenic trisulphide, the average single pulse fluence at ablation threshold is found to be >100 ...

In vivo multiphoton‐microscopy of picosecond‐laser‐induced optical breakdown in human skin

open access: yesLasers in Surgery and Medicine, 2017
Improvements in skin appearance resulting from treatment with fractionated picosecond‐lasers have been noted, but optimizing the treatment efficacy depends on a thorough understanding of the specific skin response.

Formation of Laser‐Induced Periodic Surface Structures on Titanium Alloy Using a Picosecond Laser: Dependence on Fluence and Number of Laser Pulses

open access: yesAdvanced Materials Interfaces, EarlyView.
Laser treatment of materials is a versatile technique for generating ordered surface structures. Nevertheless, such structures are the result of laser parameters such as laser pulse fluence. We demonstrate that homogeneous low special frequency laser‐induced periodic surface structures are contingent on both single and effective fluence dose and can be

Evaluation of Combined Treatment With Picosecond Laser and Acoustic Shock Wave Therapy for Tattoo Removal: A Prospective Randomized Controlled Trial

open access: yesJEADV Clinical Practice
Background Laser tattoo removal traditionally employs q‐switched and picosecond lasers, which require multiple sessions. Besides the selective photothermolysis that laser devices offer, the photoacoustic effect by acoustic pulse devices may provide ...

Ultrafast optical rotations of electron spins in quantum dots [PDF]

open access: yes, 2009
Coherent manipulation of quantum bits (qubits) on time scales much shorter than the coherence time is a key prerequisite for quantum information processing.

Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices

open access: yesAdvanced Materials Technologies, EarlyView.
Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...

Generation of frequency shifted picosecond pulses with low temporal jitter [PDF]

open access: yes, 1984
Transient stimulated Raman scattering is used for the generation of a frequency shifted picosecond light pulse; part of this Raman shifted pulse is subsequently coherently scattered at a material excitation of a second Raman cell.

Alopecia Totalis Treated with 1064 nm Picosecond Nd:YAG Laser: A Case Report

open access: yesApplied Sciences, 2019
Alopecia areata (AA) is an autoimmune disorder causing nonscarring hair loss. Alopecia totalis (AT), the severe form of AA, is usually refractory to many first-line treatments including topical and intralesional corticosteroids and topical immunotherapy.
