We present a double sided, single pass Michelson heterodyne interferometer for dimensional stability measurements. In preliminary measurements, the double deadpath configuration (no sample) showed better than ±1.5 nm (2σ) over 13 hours. A 30 mm stainless gauge block was then measured with a stability of ±1.2 nm (2σ) over 9 hours. The interferometer was then moved to a facility capable of measuring in vacuum. In a pressure sealed environment, but not vacuum, the interferometer stability was better than ±0.6 nm (2σ) over 23 hours. Using a Fourier analysis on this drift measurement, the limiting factor is the slight spatial gradients in the refractive index. With relatively large air paths greater than 400 mm, refractive index fluctuations on the order of parts in 10 9 are needed to cause this drift.

“…Essentially, there are three stabilization techniques to stabilize a He-Ne laser based on its own gain profile: Lamp-Dip Stabilization, Two-mode Stabilization and Zeeman Stabilization ( § 9.2 in [11]). Other techniques, such as the Three-Mode Stabilization [12] and the utilization of the secondary beat frequency, turned out to be rather complex and suffer a niche existence. The authors refer to a suitable review publication [11] for a deeper insight into this topic, which would go beyond the topic of this article.…”

We propose a wavelength standard for highly precise dimensional measurements. An internal-mirror helium-neon laser is offset-locked to a frequency comb line in order to carry out a secondary standard with reduced phase noise and high optical power. Additional lasers can be traced back to this secondary standard, which will enable us to disseminate the accuracy and stability to the metrology lasers of our nanopositioning and -measuring machine, the so-called NPMM-200. First measurements revealed that the stability of the secondary standard is restricted by the time standard of the optical frequency comb to a value of 2.4·10 -12 (τ = 1 s), which is a significant improvement in comparison to the stability of the existing metrology lasers. In further measurements a metrology laser was locked onto the secondary standard with a relative instability of 0.6·10 -15 (τ = 1000 s).

“…In addition, after 1973, Bannet et al achieved the stability of 2 9 10 -8 (1609) by the heating coil method [4]. Since then, passive and active methods with different designs and techniques have been developed for frequency and amplitude stabilization of He-Ne lasers, which has resulted in the stability of *10 -16 (*10 10 9) [5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…Although the use of fan apparently prevents the temperature rise of the laser tube, the least disruption in the fan revolution adjustment severely affects short-term stability. To control the length of laser cavity, Ellis et al utilized a Peltier thermoelectric cooler in 2010 and 2012 [16,17]. They used a mixed mode within the optical cavity to stabilize the absolute laser frequency.…”

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. Measurements indicate that there are an optimal temperature (23°C) and an optimal discharge current (5.5 mA) of laser tube for which the laser light power is separately maximized. To prevent the effect of fluctuation of discharge current on the laser stability, an adjustable current source is designed and fabricated so that the current is set to be optimal (5.50 ± 0.01 mA). To isolate the laser tube from the environment, the laser metallic box connected to two Peltier thermoelectric coolers is surrounded by two thermal and acoustic insulator shells. The laser has two longitudinal modes very often. Any change in the frequency of longitudinal modes at the optimal temperature is monitored by sampling the difference of longitudinal modes' intensities. Therefore, using a feedback mechanism, the current of thermoelectric coolers is so controlled that the frequency of modes stays constant on the gain profile of the laser. The frequency stability is measured equal to 1.17 9 10 -9 (*27009) for less than 1 min and 2.57 9 10 -9 (*12009) for more than 1 h.
