Lasers for lidar and more

John Ambroseo, President and CEO of Coherent.

Business Forum: Laser markets evolve, price battles continue—an interview with John Ambroseo

QCL-based infrared spectroscopic ellipsometer rapidly acquires data

Large-field cryogenic objective mirror has nearly diffraction-limited performance

Metasurface optic for Gaussian beams accepts a nonplanar input beam

Nanoparticle-embedded stretchy optical fibers monitor body temperature

Frequency-comb Sources: One microresonator-based soliton comb replaces multiple WDM lasers

A fast, low-cost, highly sensitive diffuse optical imaging system acquires optical transmission images dorsally to provide objective, quantitative analysis for rheumatoid arthritis (RA) diagnosis and monitoring.

Spectroscopy/Optical Imaging: Fourier-transform analysis helps optical method improve RA detection

Several rotationally symmetric cavities are etched into a silicon wafer for glassblowing of 0.9-mm-diameter (left) and 1.8 mm (right) axicons.

Optical Fabrication: Glassblowing technique creates arrays of axicon lenses

Shown are tuning curves for three quantum dots positioned on the waveguide at the locations shown in the inset, to achieve identical emission (a). High-resolution Fabry-Perot interferometer measurements show all three quantum dots simultaneously from an output coupler with identical emission wavelength (b).

Quantum Sources: Squeezed quantum dots create coherent streams of quantum-ready photons
