LASERS OF
GNIK-3 SERIES
Lasers of GNIK type represent gas helium-neon lasers of
continuous operation mode with emission in infrared band of optical spectrum at
1.15 μm, 3.39 μm, 5.4 μm wavelengths, multimode with emission power in range 1.5
mW to 23.0 mW, having polarized and non-polarized emission.
The lasers
demonstrate all advantages of low-intensity and highly directional monochromatic
emission at spectral lines, which are congruent with absorption lines of
environment-damaging releases of industrial facilities, including methane,
nitrogen oxide etc. Such matching allows taking them as a basis for development
of highly effective gas analyzers and gas existence or leakage detectors. In
addition, they may be used in covert alarm systems and fiber-optic
communications.
Laser comprises of laser head and power supply. Coaxial tube,
which at he same time represents a holder of cavity mirrors, is a basis of the
laser head design. Coaxial tube has high working gas reserve in its ballast
capacity, and this fact provides high life duration of such laser as a
whole.
