The 32734 Frequency/Intensity Stabilized Red Helium-Neon (HeNe) Laser uses a highly refined thermal compensation technique to provide an excellent balance of high output power and stability, low temperature sensitivity, and reliability. It can toggle instantly via front panel control between intensity and frequency stable modes.

In intensity stabilized mode, the HeNe laser will operate as an output power reference, with the stability of < ±0.2% (1 hour), while in the frequency stabilized mode, frequency stability as low as < ±3 MHz can be obtained over an 8 hour period. The mirror quality and performances are optimized to result in the highest quality HeNe lasers available in the market. A Proprietary design and manufacturing technology deliver a highly stabilized and quiet signal, immunity to ambient temperature drift and 1.5 mW (minimum) of clean, stable and reliable output power.

The 32734 frequency stability specifications include both a specified frequency range per time interval and per temperature interval. The short-term frequency stability of the Model 32734 makes it an excellent choice for interferometers with unequal arms. Intensity stability for surface texture characterization, velocimetry, scattering and polarization. The simple, one-button intensity lock ensures highly stable (less than 0.1% over short intervals) output power, ideal for applications where optical signal strength varies with changes in the test subject. Examples include surface scattering, profilometry, and single axis velocimetry. CE Compliant, Class 3R.

  • Stable-frequency and stable-intensity operating mode
  • Frequency drift 3 MHz maximum over 8 hours
  • Intensity stability better than 0.2% over 1 hour
