PAVOS high-power Faraday optical rotator，1010-1080nm, passive installation, up to150W, customizable

EOT high-power Faraday optical rotatoralso known asEOT high-power rotator、PAVOSFaraday optical rotator、PAVOS high-power Faraday optical rotator、EOTHigh-power optical rotator.

1）PAVOS+4mmFaraday rotator, designed to meet the needs of today's solid-state lasers;It is an ideal choice to prevent feedback and back reflection. This type of EOT high-power rotator is built upon existing systemsPAVOSOn the basis of the equipment series, flexibility and performance have been added at competitive prices.

2）PAVOS+Ultra4mmFaraday rotator provides approximately1/10Absorption and thermal lens focal shifta, in accordance with standardsPAVOS+Compared to a rotator, a rotator can theoretically provide ten times lower nonlinear refractive index. This results in less Kerr lens focal shift and lowerBIntegral to prevent catastrophic full beam self focusing.

The PAVOS+Ultra series is designed to meet high power and energy requirements1µm（1010-1080nm）Designed to meet the demands of the laser market, it has stable performance and an average power of up to150WAnd the standardPAVOS+do80WFor laser systems with long distances between amplification stages,PAVOS+UltraThe reduced thermal lens shift leads to higher coupling efficiency and simpler optical design, providing the industry's best laser reliability and performance (excellent isolation, especially at higher average power levels, while maintaining very high transmission values), relying on highVerdetThe Faraday effect of constant, low absorption materials rotates the linearly polarized light plane forward and additionally in the reverse direction45Non reciprocal rotation.

3）PAVOSThe Faraday rotator is built upon30Based on years of successful protection of lasers from unstable and potentially destructive back reflections, in order to meet high power and high energy requirements1µm（1010nmto1080nm）Designed for the needs of lasers. High power optical rotator has a high transmission rate and relies on highVerdetFaraday effect of constant, low absorption materials to rotate linearly polarized light plane forward and additionally rotate in reverse45Non reciprocal rotation of degrees.
