An electro-optic sampler utilizes a Pockels cell comprising an electro-optic crystal and a separate, removable sample carrier having an electrical transmission line affixed thereto to provide an electric field accessible to the optical sampling pulses. In the present system, a device under test is bonded to the removable sample carrier. The electro-optic crystal is not bonded to the carrier. Rather, means are provided for the electro-optic crystal to releasably engage the sample carrier and its affixed electrical transmission lines. Upon completion of a test, the carrier may be removed from the system with the device-under-test affixed thereto, and the same electro-optic crystal may be utilized in conjunction with another removable sample carrier having another device under test affixed thereto.

A CW pumped regenerative laser amplifier system capable of producing amplified laser pulses of variable repetition rate (e.g., 10 Hz to 10 kHz) with high energy stability. The regenerative amplifier is seeded by pulses injected into the optical cavity of the amplifier from a CW pumped modelocked laser.

A Pockels cell driver using a microwave triode which transfers charge from a high voltage source to a Pockels cell via a storage capacitor. The microwave tube is controlled, through its grid voltage, by two pulse amplifiers each having a plurality of tandem field effect transistor (FET) stages so as to increase the voltage across the cell in two steps having a selected delay therebetween. The driver is especially useful for seeding and extracting output pulses from a regenerative laser amplifier having the Pockels cell within its cavity. The driver may be used to operate a Pockels cell as a switchout or shutter to select a single pulse from a pulse laser such as a mode-locked Q-switched laser.
