Photoacoustic Photon Meter And Process For Measuring Photon Fluence

NIST Inventors

Kimberly A. Briggman , Chris Yung , Jeeseong C. Hwang and John H. Lehman

A photoacoustic photon meter includes: a photoacoustic generative array including carbon nanotubes disposed in a photoacoustic generating pattern, such that the carbon nanotubes: receive photons comprising optical energy, and produce thermal energy from the optical energy; and a superstratum

Non-attenuating Meter for Determining Optical Energy of Laser Light

NIST Inventors

Joshua Hadler , John H. Lehman , Matthew Spidell and Paul A. Williams

A non-attenuating meter determines optical energy of laser light in an absence of optical attenuation of the laser light and includes: a recipient mirror that: receives laser light that propagates in a primary propagation direction; produces profile light; transmits the profile light through the

A disk-shaped device is smaller than the half-dollar coin underneath it.

Smart Mirror

NIST Inventors

Alexandra (Aly) Artusio-Glimpse , John H. Lehman , Michelle Stephens , Nathan A Tomlin and Paul A. Williams

The Smart Mirror is a device that accurately measures the power of laser sources without disturbing the laser beam. This is a promising technology for accurate monitoring of output power in industrial lasers that allows power measurement during the laser’s performance of its routine operations. Such

Clockwise from upper left: bolometer for optical fiber power measurement operates at 4K, bolometer for space-based measurement of solar spectral irradiance, operates at room temperature; bolometer for continuous wave, visible/near infrared laser power measurement, operates at room temperature; bolometer for fast far infrared power calibration, operates at 4K.

NIST Radiometer

NIST Inventors

John H. Lehman and Nathan A Tomlin

This advanced radiometer is composed of a substrate, a radiation absorber placed on the substrate to absorb radiation, a thermal component placed on the substrate to change electrical resistance in response to a change in temperature of the radiometer, and a thermal link to connect the radiometer to

Optical meter 1 includes ref ector 4 disposed force member 2. Ref ector 4 is conf gured to receive radiation and to communicate a pressure of the radiation to force member 2. Ref ector 4 includes substrate 5 and ref ective surface 8. Force member 2 is conf gured to be displaced in response to receiving the force comprising the pressure, and optical meter 1 is conf gured to measure a power of the radiation, an energy of the radiation, or a combination thereof based on the pressure.

Optical Meter and Use of Same

NIST Inventors

John H. Lehman and Paul A. Williams

With this technology, high-power laser beams from 1-kilowatt (kW) up to 140 kW (and beyond) can be measured accurately using optical radiation pressure. By shining a laser beam on a reflective surface and then measuring how much the surface moves in response to the light’s pressure, researchers can
