Abstract

This paper presents the design and construction of a photonic fibre pumped OPO. The photonic fibre is used to provide high-energy pump power to an optical parametric oscillator (OPO) from a remotely sited pump laser source. Delivery of the high power radiation required for these systems is not possible using conventional fibre, as the fibres would need to be highly multimode to handle the high intensities without damage. Photonic fibres are a disruptive technology for power transmission and light manipulation/control. The fibres have the potential for supporting high irradiation powers and can operate with robust singlemode guidance. The OPO is to be used to provide a 3-5 μm wavelength source for active sensor applications. The integration of high power lasers into air platforms for remote sensing applications would therefore be facilitated, as the fibre delivery would enable the laser to be sited remotely from the sensor head and open up the possibility of several sensor types sharing the same multi-functional laser. This could reduce the complexity and hence the cost of such sensors systems leading to the potential for an affordable, robust system for military platforms.
