Mounting L-Bracket for all PPLN ovens

Thorlabs and Stratophase are pleased to present Wavelength Conversion PPLN Crystals for Frequency Doubling. These crystals can be used for frequency doubling of frequently used wavelengths, such as 980 nm, 1064 nm, 1550 nm, 1600 nm, and 2100 nm. Due to the continued success of the SHG5-1 crystal, designed for doubling short pulses with wavelengths around 1550 nm, Stratophase has been able to increase production volume and therefore reduce cost.

The Wavelength Conversion PPLN crystals for frequency doubling contain multiple gratings, each with a width of 0.5 mm, and are available in standard lengths of 1 mm and 10 mm. Refer to our Specs Tab above for detailed information about these crystals.

Nonlinear optical experiments can easily result in crystal damage from the use of excessive powers. Thorlabs is pleased to offer a low cost polishing and re-coating service to repair surface damage. In addition, custom crystals designed for other frequency doubling and mixing tasks are available upon request. Customization of the SFG PPLN crystals includes alternative lengths (0.2 mm to 40 mm), periods, and AR coating specifications. For more information, or to request a quote, please e-mail or call Tech Support at 973-579-7227.

Our PPLN crystals are supplied pre-mounted for alignment-free insertion into our PPLN temperature controlled ovens so that crystals can be interchanged easily. Accessories for the ovens make them compatible with a wide range of Thorlabs optical mounts, translation stages, and rotation stages. More information about these accessories and mounts are available in the Accessories Tab above.
