The Infrared Imaging Magnetograph (IRIM) system developed by Big Bear Solar Observatory (BBSO) has been put into preliminary operation. It is one of the first imaging spectropolarimeters working at 1565 nm and is used for the observations of the Sun at its opacity minimum, exposing the deepest photospheric layers. The tandem system, which includes a 4.2 nm interference filter, a unique 0.25 nm ...

We present a continuously tunable high-power continuous wave (CW) single-frequency (SF) Nd:YAlO3/lithium triborate (Nd:YAP/LBO) laser with dual-wavelength output, which is implemented by combining an optimized and locked etalon intracavity nonlinear loss. The obtained output powers of the stable SF 1080 540 nm lasers are 2.39 4.18 W, respectively. After to oscilating mode laser, wideband freque...

In this paper, we review the linear and non-linear dynamics of an optomechanical system made a two-membrane etalon in high-finesse Fabry–Pérot cavity. This setup has capacity to modify on demand single-photon coupling, linearized interaction regime cool simultaneously two mechanical oscillators. It is promising platform for realizing cavity optomechanics with multiple resonators. regime, analyt...
