Cryogenically Enhanced Laser-Induced Amorphous Phase Transitions in Crystalline Silicon
Conrad Kuz, Andy Lee, Shashu Tomar +6
Amorphization of silicon is crucial to applications in photonics, microelectronics and solar cell technologies. Ultrafast lasers have been used to generate amorphous silicon from c…
From pore collapse to crystal growth: ultrafast laser-induced stishovite formation in nanoporous silica
Aram Yedigaryan, Mohamed Yaseen Noor, Elena Kachan +4
The crystallization of amorphous solids under ultrafast laser irradiation represents a paradigm of non-equilibrium phase transitions, where the interplay between electromagnetic en…
Highly Efficient Second/Third Harmonic Generation in van der Waals Layered Material AgScP2S6 with Anisotropic Polarization and Temperature Dependence
Mohamed Yaseen Noor, Ryan Siebenaller, Wenhao Liu +12
Single-crystal X-ray diffraction and nonlinear optical measurements, especially second- and third-harmonic generation (SHG/THG) are comprehensively investigated for the van der Waa…
Mimicking the earth core conditions with ultrafast laser materials interaction
Mohamed Yaseen Noor, Aram Yedigaryan, Gabriel Calderon +6
Ultrafast lasers create extreme, non-equilibrium thermodynamic conditions that can transiently reach pressures and temperatures comparable to interior core of the earth. Here we sh…
Single shot multi-time frame imaging of plasmas with a frequency tagged GHz pulse train
Justin Twardowski, Conrad Kuz, Mohamed Yaseen Noor +4
Studying plasma dynamics is crucial for understanding processes like inertial confinement fusion, material damage, and shockwave formation from intense laser or current interaction…
Ferroelectric Epsilon-WO3 Nanoparticles and Its Bipolaron Driven Opto-electronic Properties at Room Temperature
Mohammad M. Rahaman, Jose Flores, Mohamed Y. Noor +6
A unique polymorph of binary tungsten trioxide, the epsilon phase of WO3, has non-centrosymmetric ferroelectric structure, typically stable below -43 degree C in bulk. We have stab…
