A pulsed tunable dye laser has been described which can generate intense, highly monochromatic, tunable radiation throughout the visible spectrum. Pumped by a nitrogen laser, it achieves bandwidths of less than 0.004 Angstroms with the help of a diffraction grating in Littrow mount together with an intracavity beam expanding telescope and a tilted Fabry Perot interferometer. [The SCI indicates ...

The feasibility of detecting the photon-photon interaction using Fabry-Perot type laser interferometers developed for gravity wave detection is demonstrated. An “external” laser beam, serving as a refractive medium, is alternatively fed into the cavities of the interferometer and made to collide with the “internal” beams thereby inducing a measurable phase difference between them.

In this work an Intrinsic Fabry-Perot Interferometer (IFPI) based on an air-microcavity is presented. Here the air microcavity, with silica walls, is formed at a segment of a hollow core photonic crystal fiber (HCPCF), which is fusion spliced with a single mode fiber (SMF). Moreover, the spectral response of the IFPI is experimentally characterized and some results are provided. Finally, the vi...

We report a miniaturized inline Fabry-Perot interferometer directly fabricated on a single-mode optical fiber with a femtosecond laser. The device had a loss of 16 dB and an interference visibility exceeding 14 dB. The device was tested and survived in high temperatures up to 1100 degrees C. With an accessible cavity and all-glass structure, the new device is attractive for sensing applications...

We describe a self-referencing interferometer in which the wavefront and its complex conjugate are generated in a Fabry-Perot cavity having one phase conjugate mirror (PCM). The finite response time of the PCM allows one to display momentarily the moiré between old and new interferograms after a sudden change has affected the input wavefront. Results using an externally pumped BaTiO(3) crystal ...

A compact (L ≈ 5 cm) spherical Fabry-Perot interferometer with adjustable mirror spacing is used to produce interference fringes with frequency separation (c/2L)/N , N 20. These fringes are used as frequency markers in a Doppler-free saturation spectroscopy experiment. The conditions for observation of the fringes are discussed in terms of the eigenmodes of the cavity with high transverse indic...

This study examined a possibility to use a two-dimensional nonlinear Fabry-Perot interferometer (2DNFP) as a novel information processing device. Optical bistability was realized through positive or negative feedback between heat generated by absorption of light and change in resonance condition induced by temperaturedependent refractive index. Due to heat conduction in lateral direction, “turn...

of design The basic optical configuration is a power-recycled and signal-recycled Michelson interferometer with Fabry-Perot ‘transducers’ in the arms. This requires the addition of a signal recycling mirror to the suspended optics at the output ‘dark’ port, and changes in the RF modulation and control systems. The control system relies on a hierarchy of actuators in the seismic and suspension s...

We have considered some results concerning gas and stars kinematics of nearby galaxies recently obtained on the SAO RAS 6m telescope using the panoramic spectroscopy methods. The circumnuclear regions of the galaxies were observed with integral-field spectrograph MPFS. The large-scale ionized gas kinematics was studied with the scanning Fabry-Perot interferometer (FPI) in the multi-mode focal r...

An intrinsic Fabry-Perot interferometeric sensor based on a microfiber has been demonstrated. The micro-size suspended core is created by chemical etching a photonics crystal fiber, of which the cladding has a micrometer-spaced, hexagonal array of air holes. The sensing head is fabricated by chemical etching a short section of photonics crystal fiber spliced with a single mode fiber. The temper...
