Portable, microbench light sources based on diode lasers emitting at two wavelengths improve the ratio of signal-to-background noise for chemical analysis without wavelength calibration.
Atomic physics techniques could enable a new design for gravitational wave detectors, allowing for a shorter baseline length and eliminating the need for multiple baselines.
Sensitive, low-cost silicon carbide-based gas sensors can detect toxic emissions and hazardous nanoparticulate matter in previously untenable environments.
Optical instruments capable of measuring polarization properties without moving parts avoid misalignments and make fast measurements with high accuracy.
