To measure the degree of polarization of a plasma emission, a polarization-resolved UV-visible Czerny-Turner-type spectrometer was designed and constructed. For a high spectral resolution, F=1 m mirrors were used as a focusing and collimating mirrors and the incidence angles to the mirrors were determined to eliminate coma. The effect of astigmatism was reduced by designing the incidence angles...

We report on experimental observation of radiation-pressure induced effects in a high-power optical cavity. These effects play an important role in next generation gravitational wave (GW) detectors, as well as in quantum non-demolition (QND) interferometers. We measure the properties of an optical spring, created by coupling of an intense laser field to the pendulum mode of a suspended mirror; ...

The MEMS (Micro-Electronical Mechanical System) scanning mirror is an optical MEMS device that can scan laser beams across one or two dimensions. MEMS scanning mirrors can be applied in a variety of applications, such as laser display, bio-medical imaging and Light Detection and Ranging (LiDAR). These commercial applications have recently created a great demand for low-driving-voltage and low-p...

We present a novel method of machining optical fiber surfaces with a CO₂ laser for use in Fiber-based Fabry-Perot Cavities (FFPCs). Previously FFPCs were prone to large birefringence and limited to relatively short cavity lengths (≤ 200 μm). These characteristics hinder their use in some applications such as cavity quantum electrodynamics with trapped ions. We optimized the laser machining proc...

We have investigated the optical properties of surface-micromachined polycrystalline silicon reflectors within the visible spectral range at five different wavelengths. The measurement results of the reflectivity of various microreflectors at four different incident angles (20 , 30 , 45 , and 60 ) are presented. Optical properties of microreflectors realized using the multiuser MEMS process (MU...

The possibility of phase conjugate mirrors (PCM's) with reflectivities exceeding unity was predicted by Yariv and Pepper, 1 and subsequently observed by Bloom, Liao, and Economou, and by Pepper, Fekete, and Yariv. 3 The properties of resonators with PCM's have been studied experimentally and theoretically. Early work employed high intensity Q switched lasers as the pump beams. Because of formal...

Interferometric gravitational wave detectors operate with high optical power in their arms in order to achieve high shot-noise limited strain sensitivity. A significant limitation to increasing the optical power is the phenomenon of three-mode parametric instabilities, in which the laser field in the arm cavities is scattered into higher-order optical modes by acoustic modes of the cavity mirro...

2014 The development of multilayered mirrors for the soft X-ray range allows us to bulld diagnostics capable of imaging dense plasmas at radiation energies less than or equal to 100 eV. Multilayered mirrors have particular applications in laser fusion research. In this area, such instrumentation allow us to study the overcritical zone of laser created plasmas. In this zone where the electromagn...
