Improved optical control of molecular quantum states promises new applications including chemistry in the quantum regime, precision tests of fundamental physics, and quantum information processing. While much work has sought to prepare ground state molecules, excited states are also of interest. Here, we demonstrate a broadband optical approach to pump trapped SiO+ molecules into pure super rotor ensembles maintained for many minutes. Super rotor ensembles pumped up to rotational state N = 67…

Method for preparation and readout of polyatomic molecules in single quantum states
Polyatomic molecular ions contain many desirable attributes of a useful quantum system, including rich internal degrees of freedom and highly controllable coupling to the environment. To date, the
Manipulation of individual hyperfine states in cold trapped molecular ions and application to HD+ frequency metrology.
TLDR
Advanced techniques for manipulation of internal states, standard in atomic physics, are demonstrated for a charged molecular species for the first time and the highest spectral resolution is obtained so far in the optical domain on a molecular ion species.
Cooling of a Zero-Nuclear-Spin Molecular Ion to a Selected Rotational State.
TLDR
The rotational level spacing and the large dipole moment of SiO+ allows for direct manipulation by microwaves, and the absence of hyperfine structure in its dominant isotopologue greatly reduces demands for pure quantum state preparation.
Optical Pumping and Vibrational Cooling of Molecules
TLDR
A broadband femtosecond laser is applied that redistributes the vibrational population in the ground state via a few electronic excitation/spontaneous emission cycles and observes a fast and efficient accumulation in the lowest vibrational level, ν = 0, of the singlet electronic state.

Stationary molecules in well-defined internal states are of broad interest for both physics and chemistry. This includes tests of fundamental physics through metrology such as measurement of the
Probing molecular potentials with an optical centrifuge.
TLDR
The revival period of the rotational revivals is measured as a function of the centrifuge-induced rotational frequency and compared with the numerical calculations based on the known Morse-cosine potentials.
Rotational spectroscopy with an optical centrifuge.
TLDR
A new spectroscopic method for studying electronic transitions in molecules with extremely broad range of angular momentum, using the technique of resonance-enhanced multi-photon ionization to record the spectrum of multiple ro-vibrational transitions between X(3)Σg(-) and C( 3)Πg electronic manifolds of oxygen.
Rovibrational optical pumping of a molecular beam
Cooling the rotation and the vibration of molecules by broadband light sources was possible for trapped molecular ions or ultracold molecules. Because of a low power spectral density, the cooling
All-optical triple resonance spectroscopy of Na2 and scheme for state-selective formation of highly rotationally-excited diatomic molecules
A scheme is proposed for making highly rotationally excited diatomic molecules (“super rotors”) in their ground vibrational and electronic state, e.g., 6Li2X 1Σg+ (v=0,J⩾115) where the rotational
Broadband optical cooling of molecular rotors from room temperature to the ground state.
TLDR
This work cools trapped AlH(+) molecules to their ground rotational-vibrational quantum state using an electronically exciting broadband laser to simultaneously drive cooling resonances from many different rotational levels.
