A laser diode’s wavelength isn’t fixed. As it heats up, the semiconductor’s bandgap shrinks and its cavity shifts, pushing emission toward the red, sometimes in sudden mode hops. Learn why it happens, why drive current matters...
Wavelength and optical power are only the starting point when specifying an OEM laser. Beam size, divergence, working distance, modulation, packaging, thermal conditions, electrical interfaces, and production requirements can all determine whether a laser will actually...
Why are some laser beams circular while others are elliptical? Learn how laser diode geometry, diffraction, anamorphic optics, fiber coupling, and DPSS architectures determine beam shape.
Explore how separated-geometry laser modules reduce optical-head size, support SWaP goals, and provide greater packaging flexibility in space-constrained systems.
A technical look at how lasers are used in anti-counterfeiting, from direct laser marking and holography to fluorescence, Raman signatures, speckle, and optical PUFs
A practical way to pick wavelength, power, and module style—so you spend less time fighting fluorescence and drift and more time collecting usable spectra.
Fluorescence microscopy is an illumination-controlled spectroscopy experiment with spatial readout. Precision lasers are the backbone of such techniques. Considerations include wavelength placement vs dye set, power stability over long time series, modulation/blanking interfaces, polarization management (TIRF...
Somewhere between a Thanksgiving recipe and a directed-energy test plan lies this experiment: using industrial and research-grade lasers to roast a turkey with obscene levels of precision. Do not try this at home (or in your...
How a power supply prototype grew into an Arkansas-born photonics manufacturer serving some of the world's most important industries.
Learn how our lasers power modern remote sensing—from LiDAR and DIAL to Raman, LIF, and CRDS—and which specs actually matter for mission‑critical measurements.
