By adjusting the CCD camera position, we can locate the position of the focal point of the helium-neon laser
beam and we can measure the focal length of the thermal lens.
treatment transforms fibroblasts into myofibroblasts.

with 5 J/[cm.sup.2] stimulates proliferation and expression of interleukin-6 in diabetic wounded fibroblast cells," Diabetes Technology and Therapeutics, vol.
At INP, the study of lasers with direct nuclear pumping began in 1980 after the appearance of several publications regarding the creation of low-threshold lasers: these publications concerned an Ar-Xe mixture with a lasing threshold of 8 x [10.sup.12] n/[cm.sup.2]s  and continuous helium-neon lasers
at neutron fluxes of 2 x [10.sup.11] n/[cm.sup.2] s .
Effect of low-level helium-neon laser
therapy on histological and ultrastructural features of immobilized rabbit articular cartilage.
Instead of a dynamic Michelson interferometer with moving mirrors, it has a static, fiber-based Mach-Zehnder interferometer, and in place of a Helium-Neon laser
, it uses a NIST-traceable gas-absorption cell.
The inspection technique being developed by Argonne uses a low-power helium-neon laser
, similar to those found in grocery checkout counters.

Of the recommended radiations, that of the iodine-stabilized helium-neon laser
is the most widely used for practical realization of the meter.
The computer-to-plate imager comes with either a helium-neon laser
for red-sensitive silver-halide metal plates or frequency-doubled YAG laser for green-sensitive sliver-halide or photopolymer plates.
Common exciting wavelengths are 488.0 and 514.5 nm from an argon ion laser, 614.7 nm from a krypton laser and 632.8 nm from a helium-neon laser
. The laser exciting line occurs in the spectrum as Rayleigh scattering.
In this system, the beam from a helium-neon laser
in the vibrometer's sensor head probes the test object's surface, reflecting back to the sensor head, where it is analyzed in a Michelson interferometer.
