Electro-optical crystals for detection of broadband THz pulses

Featured inquiry:
EO crystals for broadband THz detection:
- GaP crystal, 110-cut 10x10x0.1 mm mounted in a 1'' holder
- ZnTe crystal, 110-cut 10x10x0.1 mm mounted in a 1'' holder

We will use visible pulses tunable from 650 to 900 nm with a maximum energy per pulse of about 3 microJ (slightly depending on the wavelength), 50 fs duration and with a repetition rate of 50 KHz. These are generated with an OPA taking 100 microJ input from a Pharos laser working at 50 KHz. The crystals will be used as electro-optical crystals for detection of broadband THz pulses.
