1053nm Singlemode PM Fiber Bandpass Filter for Pulse Power

DESCRIPTION
Haphit provides fiber based passive components. The Bandpass Filter is made by thin film coating and micro-optics package technology with Polarization Maintaining (PM) fiber in and PM fiber out. It features flat-top spectrum, high Suppression Ratio and high Extinction Ratio. The Bandpass Filter will pass the signal light while block the unwanted/ASE light. The pulse power version is specially designed to withstand both high average power and high peak power for pulse laser, while at the same time maintaining high performance and stability. Y Type or X type is strongly recommended to guide out high power ASE/unwanted light out. Customer can select only slow axis working (High ER Type) or both axis working option. Various pass bandwidth and fiber types are available, customized on bandwidth and consigned fiber type are also available on request.
