Helium Neon Laser System Manual (1-5 mW)
N-LGP-173 rev 4_20_1 Spec Sheet
HeNe Linewidth, Coherence, and Center Frequency
The N-LGP-173 Green HeNe Laser generates a 500:1 linearly polarized output of 0.5 mW (minimum) at 543 nm. Longitudinal mode spacing is approximately 373 MHz with the spectral bandwidth being approximately 1630 MHz (FWHM). Utilizing enhanced designs and superior optical components these HeNe lasers deliver unsurpassed operational stability and lifetimes. The mirror quality and performances are optimized to result in the highest quality HeNe lasers available in the market. These high-performance lasers are supported by a one-year warranty and are available off-the-shelf. CE compliant, IEC Class 3R.The power supply is included. A spare or replacement laser head and power supply can be purchased seperately off-line. The laser head model is N-LGP-173-H, and the power supply model is N6-LPL-903-065.
543 nm Output Power from 0.5 mW to 2.0 mW
We offer green HeNe lasers with output power levels ranging from 0.5 mW to 2.0 mW. The power supply is included with the green HeNe laser head.
Random or 500:1 Polarization
We have models whose outputs are either polarized or randomly polarized. Due to the random fluctuation of the polarization state of the beam, it is not recommended to use a polarizer with a random polarization laser for applications where polarized light is required. The laser with the polarized output has a vertical polarization direction, when the shutter control is shown at the top.
Utilizing enhanced designs and superior optical components these lasers deliver unsurpassed operational stability and lifetimes. The mirror quality and performances are optimized to result in the highest quality HeNe lasers available in the market. These high-performance lasers are supported by a one-year warranty and are available off-the-shelf.
HeNe Lasers use a mixture of Helium and Neon gas as the gain medium excited by an electrical discharge. Helium Neon gas lasers are based on a mature and well understood technology that offers a cost effective laser source with fundamental Gaussian beam quality, and ease of use. Green HeNe lasers offer a stable optical output over lifetimes greater than 10,000 hours and are insensitive to optical feedback.
ULM Series cylindrical laser mounts attach to 340-RC and 370-RC rod clamps and provide a convenient way to attach these HeNe lasers to Newport stages, tables, or breadboards. For N-LGP and N-LGR series, please mount the laser at either end of the body indicated by shading.
