Melt Pool and Keyhole Behavior Analysis for Deep Penetration Laser Welding [PDF]

open access: yes, 2010
One usually defines the main characteristic of the welding performances of a given laser system by its “penetration curve” that corresponds to the welding depth as a function of the welding speed Vw for a given set of operating parameters.

Discretely Tunable Multiwavelength Visible Laser Based on Cascaded Frequency Conversion Processes

open access: yesApplied Sciences, 2020
We demonstrate a discretely tunable multiwavelength visible laser through second harmonic generation (SHG) and sum frequency generation (SFG) of multiorder Stokes lasers generated from an external Raman laser oscillator.

Ultrastable Multiclock Frequency Injection and Dissemination in a Ring Fiber Network

open access: yesIEEE Photonics Journal, 2017
Owing to the characteristics of ultralow loss and antielectromagnetic interference, using optical fiber to deliver time and frequency signals has been a preferred choice for high-precision clock dissemination and comparison.

Compact 50 W All-Solid-State Picosecond Laser System at 1 kHz

open access: yesApplied Sciences, 2020
Compact, stable, high-power and high repetition rate picosecond laser systems are excellent sources for optical parametric chirped pulse amplification systems and laser satellite ranging systems. Compared with the traditional complex high-power amplifier,

Retrievals of vertically resolved aerosol microphysical particle parameters with regularization from spaceborne Aerosol and Carbon dioxide Detection Lidar (ACDL) [PDF]

open access: yesAtmospheric Measurement Techniques
Using an improved regularization method, we attempt to derive microphysical parameters (effective radius reff, surface area concentration St, volume concentration Vt) of aerosol particle size distribution directly from the detection results of Aerosol ...

Π‐Electron‐Extended Porphyrin‐Linked Covalent Organic Framework for a Q‐Switched All‐Solid‐State Laser

open access: yesAdvanced Photonics Research, 2023
Herein, a new π‐electron‐delocalized building block (ProPh‐4CHO) is reported for the construction of a π‐electron‐extended porphyrin/pyrene‐linked covalent organic framework (ProPh‐PyTA‐COF) for use as a saturable absorber (SA) in a Q‐switched all‐solid ...

Characterization of single-crystal synthetic diamond for multi-watt continuous-wave Raman lasers [PDF]

open access: yes, 2012
A continuous-wave diamond Raman laser is demonstrated with an output power of 5.1 W at 1217 nm. This Raman laser is intracavity pumped by a side-pumped Nd:YLF rod laser: a 43-fold brightness enhancement between the Nd:YLF and diamond Raman lasers is ...

Diode-Pumped Solid-State Q-Switched Laser with Rhenium Diselenide as Saturable Absorber

open access: yesApplied Sciences, 2018
We report a solid-state passively Q-switched Nd:YVO4 laser adopting rhenium diselenide (ReSe2) as saturable absorber (SA) materials. ReSe2 belongs to a type of transition metal dichalcogenides (TMDs) materials and it has the weak-layered dependent ...

High beam quality 400W practical all-solid-state laser for laser beam texture [PDF]

open access: yes, 2010
A high-average-power and high-beam-quality diode-side-pumped solid-state laser was designed carefully for laser beam texture. By using of low concentration Nd:YAG crystals with thermally near-unstable resonator design and two-rod birefringence ...
