DKDP Pockels Cells – Electro-optic Product- Customized Products
DKDP (KD2PO4) Pockels Cells, also known as potassium deuterium phosphate pockels cells or DKDP pockels cells. It is a pockels cells device with excellent overall performance.
DKDP crystals have a low optical loss, high extinction ratio, good electro-optical properties, and good tolerance to the environment, etc. They can be used in these fields:
Electro-optical Q-switches
High-speed camera switches
Military, and aviation laser systems
Dye lasers 800 nm two- and three-fold
1064 nm two-, three- and four-fold fields
Ambient temperature range: 10~50 degrees, temperature change should not exceed 5 degrees every 20 minutes, ambient humidity: <40%. Try to use a humidity control device (desiccant and desiccator). When not in use, please store it in a dry box.
Note:
$100 is a deposit, not the final price of the product. Please contact us for price if needed.
