Picosecond Laser Chemistry in Supersonic Jet Beams [PDF]

open access: yes, 1983
In this review we describe the development and the applications of the picosecond-jet technique, which utilizes a picosecond laser and a supersonically-cold jet beam of large molecules.

Terahertz electrical writing speed in an antiferromagnetic memory [PDF]

open access: yes, 2018
The speed of writing of state-of-the-art ferromagnetic memories is physically limited by an intrinsic gigahertz threshold. Recently, realization of memory devices based on antiferromagnets, in which spin directions periodically alternate from one atomic ...

Subsurface Fractional Ablative Resurfacing of a Periareolar Scar Using 1,064-nm Picosecond Laser with Micro-Lens Array [PDF]

open access: yesArchives of Aesthetic Plastic Surgery, 2018
Although picosecond lasers were invented as an effective treatment of pigmented lesions, the Food and Drug Administration has also approved picosecond lasers with fractional mode for treating acne scars and wrinkles on the face.

3.8-μm Mid-Infrared Laser Quasi-Synchronously Pumped by a MOPA Structured Picosecond Yb Fiber Amplifier With Multi-pulse Operation

open access: yesIEEE Photonics Journal, 2016
A picosecond pulsed mid-infrared laser with multi-pulse operation is experimentally demonstrated. This mid-infrared laser was composed of a fiber laser pumped optical parametric oscillator (OPO).

Beating of exciton-dressed states in a single semiconductor InGaAs/GaAs quantum dot [PDF]

open access: yes, 2009
We report picosecond control of excitonic dressed states in a single semiconductor quantum dot. A strong laser pulse couples the exciton and biexciton states, to form an Autler-Townes doublet of the neutral exciton transition.

Picosecond and sub-picosecond pulse generation in semiconductor lasers [PDF]

open access: yesJournal de Physique III, 1992
Generation of short optical pulses in semiconductor lasers is of practical interest for an increasing number of applications. It is also of fundamental interest because of its tight relation with the field of semiconductor laser dynamics. After an introductory review, we compare the performances of gain-switching, Q-switching and mode-locking ...

Nanostructuration of Thin Metal Films by Pulsed Laser Irradiations: A Review

open access: yesNanomaterials, 2019
Metal nanostructures are, nowadays, extensively used in applications such as catalysis, electronics, sensing, optoelectronics and others. These applications require the possibility to design and fabricate metal nanostructures directly on functional ...

Measurement and Modeling of Infrared Nonlinear Absorption Coefficients and Laser-induced Damage Thresholds in Ge and GaSb [PDF]

open access: yes, 2010
Using a simultaneous fitting technique to extract nonlinear absorption coefficients from data at two pulse widths, we measure two-photon and free-carrier absorption coefficients for Ge and GaSb at 2.05 and 2.5 μm for the first time, to our knowledge ...

Near- to mid-infrared picosecond optical parametric oscillator based on periodically poled RbTiOAsO4 [PDF]

open access: yes, 1998
We describe a Ti:sapphire-pumped picosecond optical parametric oscillator based on periodically poled RbTiOAsO4 that is broadly tunable in the near to mid infrared.
