PPLN crystals by application
 |
Optical Parametric oscillators and amplifiers (OPO's & OPA's) for frequency down conversion e.g converting a 1064nm Nd:YAG laser to mid infrared 2-5 micron sources. |
 |
Second Harmonic Generation (SHG) Allows a laser to be converted to half its wavelength e.g converting a 1064nm Nd:YAG to 532nm visible, or 980nm laser diodes to 480nm blue sources, or 1550nm lasers to 775nm sources |
 |
Difference Frequency Generation (DFG) Combine two lasers at different wavelengths to generate longer wavelengths e.g. Using a tuneable Ti Sapphire laser and Nd:YAG to generate tuneable light at 2.5 – 4..5µm |
 |
Sum Frequency Generation (SFG) Combine two lasers to generate shorter wavelengths e.g. Using a tuneable Ti Sapphire laser and 1550nm fibre laser to generate tuneable light around 520nm. |
| Custom crystals. Stratophase offer a full design service to provide the correct crystal for your application. e.g. high power operation, short pulsed operation, other wavelengths, custom AR coatings. |
These crystals be used for applications in Displays, Biomedical & photonics research, remote sensing, defence and security and a host of other areas.
