Thirty minutes later the laser without locking continued to.

He ne laser frequency stabilization.

In frequency stabilized mode the laser will keep its lasing frequency i e wave. The results of beating with an iodine stabilized he ne laser show that a relative uncertainty δ f f of 4 3 10 9 in 5 months a frequency fluctuation of 1 4 mhz and an allan deviation of 6 10 11 τ 10 000 s in 20 h are obtained. Plots of intensity of the two modes versus time were graphed to observe the laser behavior. Frequency stabilized he ne laser.

Frequency stabilized he ne laser. From gure 4 it can be observed the intensity of the two modes of the laser uctuates for the rst ve minutes when the laser was turned on. We have developed a frequency stabilization system for the he ne laser using an external fabry perot cavity which is locked to the lamb dip of the laser. Our 633 nm frequency intensity stabilized helium neon lasers use a highly refined thermal compensation technique to provide an excellent balance of high output power and stability low temperature sensitivity and reliability.

Thorlabs stabilized helium neon laser with a center wavelength of 632 991 nm allows for either frequency or intensity stabilization necessary for many spectroscopy interferometry and wavemeter applications. An approach for frequency stabilization of an ambience isolated internal mirror he ne laser 632 8 nm utilizing temperature control of the laser tube with peltier thermoelectric coolers is demonstrated. The stabilization method is based on anomalous dispersion of the gain medium.
