LN Pockels Cell
LN Pockels Cell
The LN Pockels cell uses a lithium niobate (LiNbO3) crystal as an electro-optic Q-switch. Four standard sizes are available from 2.5 mm to 9 mm clear aperture, all at 1064 nm with Au/Cr electrodes. Near-stoichiometric LN or MgO:LN can be selected, and cylindrical shells can be customised.
Features
- Au/Cr electrodes for stable operation
- Insertion loss < 3 %
- Wavefront distortion λ/8 @ 632.8 nm
- Extinction ratio 200:1 (5 mm section)
- LIDT from 100 to 200 MW/cm² depending on aperture
- Near-stoichiometric LN or MgO:LN available; cylindrical shells on request
