Green Helium-Neon (HeNe) Lasers

Our green HeNe lasers offer TEM₀₀ and higher order mode structures at 543 nm in either linear or random polarization. The 543 nm wavelength is highly visible (near photopic vision peak), making it ideal for alignment applications. Green He Ne lasers are also used in many biophotonic applications. We offer products with power levels ranging from 0.5 mW to 2.0 mW.

543 nm wavelength power from 0.5 - 2 mW
Polarized or randomly polarized output
Optimized cavity mirror performance and quality
Excellent power and thermal stability due to robust tube design
Low beam pointing drift (after 20 minute warm-up)
CE compliant

Features

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.

HeNe Laser Mounting

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.

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.

Optimized Cavity Mirror Performance

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 Laser Advantages

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.
