Composite Photopolymerization with Diode Laser

open access: yesOperative Dentistry, 2007
Clinical Relevance Many curing lights that are present in clinical practice today cause the clinician to wonder which curing unit is best for the photopolymerization of dental light curing materials. This study introduces the blue diode laser photopolymerization of composite materials, which, if acceptable for clinical use, offers the ...

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum

open access: yesAdvanced Materials, EarlyView.
Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Bias‐Field Free Single‐Frequency CW‐ODMR of Nitrogen‐Vacancy Centers in Diamond for the Detection of Transient Electrical Signals

open access: yesAdvanced Materials Interfaces, EarlyView.
Simplified quantum sensing technique for the detection of short electrical signals occurring in neuronal signaling or bioinspired technologies. We demonstrate a single frequency continuous‐wave optically detected magnetic resonance (CW‐ODMR) approach to sense signals that can be as short as 0.2 ms.

Full characterization of low-power picosecond pulses from a gain-switched diode laser using electro-optic modulation-based linear FROG

open access: yes, 2007
We use a linear frequency-resolved optical gating technique based on electrooptic modulation to fully characterize for the first time the highly chirped pulses from a 1.06 µm Fabry-Perot laser diode and design a chirped fiber Bragg grating to provide ...
