Gallery Group picture (May 2023) View of the “Pharos” section of the lab baking vacuum chamber Transient-grating + THz setup pathway of 515nm laser beam in an optical setup Dusan showing how to do it 2D-THz setup under construction (c. 2022) make-and-break: characterizing mid-IR output from on OPA with FTIR Collaboration with Waitukaitis group: quantifying light-induced surface charging under the hood: re-gen cavity of Spectra-Physics Solstice Ace laser system Ricardo of Oxford Instruments helping Chao to bring our B=7 Tesla magnetic closed-cycle optical cryostat (OxInst SpectromagPT) back to life after an accident (now we know that power decay law is nearly not as fast as an exponent:)) under the hood: optical compressor of Light Conversion Pharos laser system Probing surface acoustic waves (SAW) in diamond optically.
