| Title: |
JILA; Radiation Instrument |
| Description: |
JILA instrument for generating terahertz radiation. Ultrafast pulses of near-infrared laser light enter through the lens at left, striking a semiconductor wafer studded with electrodes (transparent square barely visible under the white box connected to orange wires) bathed in an oscillating electric field. The light dislodges electrons, which accelerate in the electric field and emit waves of terahertz radiation. The radiation bounces off the reflective dishes at the bottom and top of the photo and hits the circular detector on the right.
