Diamond F-SMA PSi connectors are mainly used for medium to high power laser delivery in industrial, medical and military applications. These connectors are designed to be used at the focal point of a laser system with the purpose of collecting maximum light and can withstand up to several hundred watts of power. They can also be used on the laser output side as well. The ferrule and the connector body are made of conductive materials that provide improved heat dissipation compared to standard multimode connectors. The free-standing fiber technology prevents the burning of epoxy and the melting of the ferrule because the fiber tip is surrounded by air. These connectors also feature an axially tunable fiber fixation that allows a precise adjustment of the fiber end face permitting the optimization of the coupling efficiency. F-SMA PSi connectors are available in mode guider and mode stripper versions. The mode guider version allows all the modes, including cladding modes, to be transmitted with minimum attenuation, resulting in less heat up and more power available at the patchcord output. The mode stripper version removes unwanted cladding modes from the fiber and is used when emphasis is made on the preservation of the Beam parameter Product (small spot diameter and low numerical aperture).
