    Overview

    Linibate produce periodically-poled lithium niobate (PPLN) in two forms: as a bulk crystal with a thickness of up to 1 mm, and as a waveguide device. PPLN devices are tailored for the production of tunable midwave-infrared (MWIR) radiation through pumping by commonly-available lasers with wavelengths near 1 micron.

    • Parameters

    Features

    Bulk PPLN devices can produce several Watts of average power between wavelengths of 2 and 4 microns. Waveguide frequency converters are fabricated using a process called Reverse Proton Exchange (RPE). The increased optical mode confinement in the resulting waveguide enables higher conversion efficiency devices that can be pumped with 100 mW class semiconductor lasers used for fiber-optic and free-space telecommunications.
