Welcome to Covesion

Perodically Poled Lithium Niobate (PPLN / MgO:PPLN)

Covesion Ltd is a leading manufacturer of MgO:PPLN and associated products.

Our proprietary production process guarantees extremely uniform vertical domains, optimising conversion efficiency and ease-of-use towards a wide range of markets and applications. We provide off-the-shelf and custom devices that can be tailored to convert your existing laser into a range of wavelengths in the 460nm-5um range.

Products

PPLN and MgO:PPLN are nonlinear optical crystals for high efficiency wavelength conversion in the 460nm – 5um range. Our proprietary poling process creates high fidelity grating periods, in 1mm thick crystals, from 4.5um to 33um and is ideal for high volume manufacture.

Facilitating easy alignment, set-up and operation, Covesion manufactures and provides the full suite of PPLN accessories, including: crystal ovens, temperature controllers, mounting kits and adaptor plates.

Projector displays

Miniaturised synthetic green lasers are readily produced using MgO:PPLN for intra-cavity harmonic generation. Providing a high wall-plug efficiency and stable operation to within a few percent, these lasers are key components in the growing laser projector market. Utilising MgO:PPLN, portable (pico) projectors are able to offer a brightness in excess of 50 Lumens under battery operation that can last for over 2 hours.
