Perodically Poled Lithium Niobate (MgO:PPLN)
Periodically poled lithium niobate(MgO:PPLN) is
a new nonlinear optical crystal. Using electric field poling fabricated
periodic domain structure, it can realize high efficiency frequency conversion
of frequency doubling, sum frequency and optical (QPM) technique. PPLN(adding 5
mol% MgO) has the features of high optical damage threshold, large
photorefractive threshold and stable performance which can be used at room
temperature. Comparing with LBO and KTP, MgO:PPLN has many advantages such as
high non-linear coefficient, smaller size, shorter manufactured cycle and
easier batch manufacture.
The
IR laser based on MgO:PPLN has many advantages, such as ultra compact, high
performance, low cost etc. Based on our company's advanced electric field
poling technology,MgO:PPLN crystal has high quality, high conversion efficiency
and its thickness could reach 2mm.
OEWindow is a supplier of MgO:PPLN crystal. The company cooperate with Chinese Academy of Sciences. Our scientists and engineers have over 8 years experience in the manufacture of PPLN for R&D, and OEM customers. Our PPLN crystals are of good quality with low prices. We
can also meet your custom needs at a reasonable price.
Application:
1.
Mid IR laser; 2. Remote
sensing; 3. Atmospheric
detecting; 4. Electro-optic
warfare. 5. Frequency doubling
