We report the results of a high-energy laser calorimeter comparison conducted by the National Institute of Standards and Technology (NIST), Boulder, Colorado and the U.S. Air Force Primary Standards laboratory (AFPSL), Heath, Ohio. A laser power meter, used as a transfer standard, was calibrated at each laboratory, sequentially, and the measurement results were compared. These measurements were...

Stationary and moving plane heat source analysis have application in several manufacturing processes such as metal cutting, spot welding, laser cutting/surface treatment (using CO2 or Argon lasers) as well as tribological applications including ball bearing and gear design [1-5]. Temperature profile and the rate of cooling at and near the surface can affect the metallurgical microstructures, th...

BACKGROUND For more than 25 years, posterior laser transverse cordotomy has been generally considered the ideal endoscopic minimally invasive procedure of choice for bilateral vocal fold immobility. The main drawback of this procedure, when compared to more aggressive "glottic aperture improvement" operations, is the high revision rates, caused by granulations, adhesion, and scar, for example. ...

We demonstrate the possibility of extending the well-established metrological performance of optical frequency-comb synthesizers to the mid-IR region by phase locking the pump and signal lasers of a difference-frequency source to two near-IR teeth of an optical comb. An uncertainty of 800 Hz (1.1 x 10(-11)) in the absolute frequencies of CO2 transitions near 4.2 microm has been measured by cavi...

We present theoretical calculations for polarization and ellipticity of high-order harmonics from aligned N2, CO2, and O2 molecules generated by linearly polarized lasers. Within the rescattering model, the two polarization amplitudes of the harmonics are determined by the photo-recombination amplitudes for photons emitted with polarization parallel or perpendicular to the direction of the same...

Progress on the development of a frequency chain devoted to the absolute frequency measurement of 127I2-stabilized lasers around 563.2 THz/532 nm is reported. The aim of this work is the improvement of the accuracy—by at least one order of magnitude—of the absolute frequency of this standard. The scheme is based on the frequency combination of two wellknown optical frequency standards, namely a...

low level lasers, cold or soft lasers: these lasers do not produce thermal effects on tissues and induce photoreactions in cellsthrough light stimulation which is called photobiostimulation. power of these lasers is usually under 250mw. the main point differentiating low level lasers and high power ones is the activation of photochemical reactions without heat formation. the most important fact...

Background/Objectives: Similar to conventional cryogen spray cooling, carbon dioxide (CO2) spray may be used in combination with laser cartilage reshaping (LCR) to produce cartilage shape change while minimizing cutaneous thermal injury. Recent ex vivo evaluation of LCR with CO2 cooling in a rabbit model has identified a promising initial parameter space for in vivo safety and efficacy evaluati...
