Radial birefringent element and its application to laser resonator design.

چکیده
We have invented a quasi-Gaussian profile-transmittance filter based on radially varying the phase retardation in a birefringent element. The radial birefringent element has been applied to resonator design and has demonstrated its usefulness in generating an improved resonator spatial-mode profile.

Polarization Analysis of Brillouin Scattering in a Circularly Birefringent Fiber Ring Resonator
A complete analysis of the eigenstate of polarization (ESOP’s) in a Brillouin fiber ring laser using fibers with a high circular birefringence is proposed in this paper. Conditions to obtain circular ESOP’s for application in a Brillouin fiber optic current sensor are highlighted as well as conditions to have stable ESOP’s for applications in other passive or active sensors. Measurements are pe...
متن کاملGeneration of Radially Polarized Beam for Laser Micromachining
A novel means of generating radially polarized light is reported in this paper. A birefringent plate was placed in a divergent or divergent portion of the laser beam for polarisation conversation. The influence of birefringent plate thickness on the purity and efficiency of radial beam conversion is studied qualitatively. This technique is robust, simple and cost effective for radial polarisati...
متن کاملSimple method for locking birefringent resonators.
We report on a simple method of locking a laser to a birefringent cavity using polarization spectroscopy. The birefringence of the resonator permits the simple extraction of an error signal by using one polarization state as a phase reference for another state. No modulation of the light or the resonator is required, reducing the complexity of the laser locking setup. This method of producing a...
متن کاملSingle-frequency operation of a Cr:YAG laser from 1332 to 1554 nm
We report the first demonstration to our knowledge of broadly tunable, single-frequency operation of a cw Cr:YAG laser. Single-frequency operation was obtained from 1332 to 1554 nm with a maximum output power of 680 mW generated at 1457 nm with 10% conversion efficiency of 1047-nm pump laser radiation. A traveling-wave ring resonator was forced to operate unidirectionally by use of Faraday rota...
