Fibers & Fiber Cables

1. Optical Fiber Cables with SMA905 Connector for Laser Beam Delivery

Our Power Fiber Cables (PFC) with PC-SMA905 connector exploit the air-gap-ferrule design, where the fiber prolongs into free space securing an epoxy-free area, where thermal energy can be safely dissipated without burning the surrounding material, making them ideal for high-power applications. A heat-sink is attached to the rear of the connector, which conducts extraneous heat away from the fiber, further reducing the possibility of breakdown.

Each cable assembly goes through the tight Quality Control with several examinations during the fabrication process, including extensive inspection of fiber tip quality by FiberCheck® technique, leading, as a result, to a special product.

• Operating Wavelength Range: 350-2500 nm

• Damage Threshold: >5J/mm² (1ms pulse at 1060 nm, & > 1.3 kJ/mm² CW at 1060 nm)

3. STG Series Photonic Microcell

Our technology is based on Hollow-Core Photonic Crystal Fiber (HC-PCF) and the process of filling the fiber with a chosen gas to offer photonic functionalities such as (i) Optical frequency conversion, (ii) Ultra-high power pulsed laser delivery (iii) Laser pulse compression or (iv) Frequency standards.

A PMC is a stand-alone and modular component that consists of a HC-PCF filled with gas and fiber terminations. The presence of gas within an optical fibre on a micron scale provides a million-fold increase in the gas-laser efficiency compared to traditional lasing methods and opens up the unique ability for functionalization. For example, with a Raman gas one can produce new wavelengths and hence create new applications. There are different variants of HC-PCF used within the PMC family of components. The Inhibited-Coupling guiding HC-PCF such as Kagome fiber produces particularly good results with a high damage threshold and a very wide bandwidth.

The PMC comes in different forms tailored to either the applications or the laser power requirements or to specific housing requirements. Below is a list of the different PMC forms we can deliver.
