HeNe Laser Selection Guide

Advantages of Helium Neon (HeNe) Lasers

  • Mature, well Understood Technology
  • Cost-effective Source of "Good" Laser Light
  • Good Beam Quality: Fundamental Gaussian
  • Stable Output Power
  • Long Lifetime (>20,000 Hrs)
  • Insensitive to Optical Feedback

Red, Green, Yellow, and Infrared HeNe Lasers

Whether you need the flexibility of multiple wavelengths from a single laser, the stability inherent in an atomic transition, or the confidence that comes from keeping an established process, there are many reasons for selecting a HeNe Laser for your research or equipment manufacturing needs.

HeNe Laser Basics

Helium-Neon or HeNe Lasers are gas lasers that use a mixture of Helium and Neon as the gain medium excited by an electrical discharge. HeNe lasers are preferred for many optics lab applications due to their ease of operation and low cost compared to other laser types.

HeNe Laser Wavelengths

A good place to start when selecting a HeNe Laser is with the wavelength.

Red HeNe Laser - 633 nm Green HeNe Laser - 543 nm Yellow HeNe Laser - 594 nm
