A phase quadrature feedback interferometer using a two- mode He-Ne laser
A new feedback interferometer is developed with which not only the magnitude but also the sign of a phase change caused by a variation in the optical path can be measured. This is an important feature, for example, in plasma diagnostics. a He-Ke laser. The two interference signals can be separately detected by virtue of the orthogonal polarisation of the two axial modes of the laser without Bre...
متن کاملNanometric Displacement Measurement System Using Three-Longitudinal-Mode He-Ne Laser
In this paper, design and simulation of a nanometric displacement measurement system is discussed. The combination of the Doppler effect and interferometry method is being used. A stabilized three-longitudinalmode He-Ne laser with o A 6328 wavelength and cm 35 cavity length is used. Its primary and secondary beat frequencies are 428.60MHz, 429.27MHz, and 670kHz, respectively. Therefore, the max...
متن کاملFrequency doubling of He–Ne laser radiation at 632.8 nm
Second harmonic generation (SHG) obtained using a potassium dihydrogen phosphate (KDP) nonlinear crystal from a CW He–Ne laser as a pump source, which emits at 632.8 nm, is reported. The SHG efficiency at the power of the He–Ne laser utilized (18 mW) and the fundamental beam waist available (0.1 mm), was evaluated theoretically; the same efficiency was measured experimentally obtaining a value ...
متن کاملEffects of Diode and He-Ne Laser on In Vitro Production of Anthocyanin in Apple Cell Suspension Culture
Plant cell cultures could be used as an important tool for biochemical production, ranging from natural pigments to pharmaceutical products. Anthocyanin is affected by a variety of factors. Light, an important plant environmental factor, influences the anthocyanin production in vegetative plant tissues. Here, we have investigated the influence of the blue laser-diode (BLD) and red laser-He Ne (...
متن کاملMonolithic, unidirectional single-mode Nd:YAG ring laser.
We have built a nonplanar ring oscillator with the resonator contained entirely within a Nd:YAG crystal. When the oscillator was placed in a magnetic field, unidirectional oscillation was obtained with a pump-limited, single-axial-mode output of 163 mW.
