Quantum & Nonlinear Optics Facilities

Quantum Entanglement Source & Detector

• Compact blue laser source pumps a nonlinear crystal

• Two IDENTICAL red photons are created when one blue photon is destroyed

• Extremely sensitive detectors measure the arrivals of the individual red photons

• Quantum statistics of the detections are captured by computer

---

Nanosecond Tunable Laser Source

• Generates intense pulses (100’s of MWs) across entire visible spectrum and well into infrared

• Ideal for studying interactions of light with matter

• Currently used for the study of quantum dots

---

Digital CCD Camera & Beam Profiler

• 14-bit digitization (16,384 levels) provides extremely accurate laser beam measurements

• Can capture even very short laser pulses using triggering capabilities

• Small (4.65 micron square) pixel sizes allow high resolution imaging

• Can image into the ultraviolet and well into the infrared in addition to the visible
