Photon Cycling and Laser Cooling of an Asymmetric Top Molecule
Grace K. Li, Giseok Lee, Jack Mango +8
We realize two-dimensional magnetically-assisted Sisyphus laser cooling of an asymmetric top molecule (ATM), calcium monoamide (CaNH). Vibrational state closure is achieved wit…

Linewidth narrowing and wideband frequency modulation of a DBR laser
Jack Roth, Andrew Christensen, Madeline Bernstein +3
We present a scheme to phase-lock a 240 mW, 852 nm distributed Bragg reflector (DBR) laser to a fixed-frequency narrow-linewidth laser with a rapidly tunable frequency offset near…

Quantum-State-Controlled Collisions of Ultracold Polyatomic Molecules
Nathaniel B. Vilas, Paige Robichaud, Christian Hallas +7
Collisions between ultracold calcium monohydroxide (CaOH) molecules are realized and studied. Inelastic collision rate constants are measured for CaOH prepared in ground and excite…
