Covesion PPLN devices are designed for efficient frequency conversion of lasers allowing you to reach wavelengths that cannot be achieved with conventional solid state lasers, diode lasers etc. For example, you can use PPLN for:

Alternatively, PPLN has often been used for around 780nm generation as a low cost and compact alternative to the Ti:Sapphire laser. This is achieved by frequency doubling a high power tunable 1560nm fibre source. Such a source can be used in microscopy systems for live-cell imaging, or terahertz time-domain spectroscopy where chemical fingerprints can be identified for homeland security applications.

PPLN devices are commonly used for high power mid-IR generation in an optical parametric oscillator. Tunable mid-IR systems are used in a wide range of microscopy imaging techniques as well as spectroscopy applications for environmental imaging. With pulse energies in excess of 1mJ, these mid-IR sources are also used in the defence industry for laser countermeasures and LIDAR systems.
