Pockels Cells

KTP (KTiOPO4) Pockels Cells 

Main features:                                                                     

♦ High damage threshold                                

♦ Deliquescent                          

♦ Operate at low frequency with high duty ratio

♦ Compared with DKDP crystals, the piezoelectric resonance is very low

♦ Small HV voltage required (2x) compared to BBO Pockels Cells

♦ Standard clear aperture: 4 x 4, 6 x 6 and 8 x 8

Typical applications:

♦ Frequency doubling and mixing of neodymium-doped lasers
