“…4), at least 10% of the molecules are photodissociated, for laser fluxes of ∼10 20 photons cm −2 s −1 . A buildup cavity with finesse of up to 1000 [27] must be implemented for the 100 W photodissociation laser at 266 nm [28]. Use of HI/DI can shift the photodissociation to 355 nm where there are more powerful lasers.…”

We describe methods for the production of spin-polarized H and D atoms from the IR-excitation and photodissociation of molecular beams of HBr, HI, and NH3 isotopes, including optical excitation schemes with partial hyperfine resolution. We discuss the extent to which the production rates may approach the IR-laser production rates of 10 21 photons s −1 , and how the production rates of conventional methods of ∼10 17 s −1 may be surpassed significantly.

“…The increased atom-laser interaction time will compensate for the lower available power compared to a pulsed laser. These new converters combined with the recent demonstration of high-power CW lasers at 243/244 nm [35,36] that can be cavity enhanced to more than 33 W of intracavity power [37] will enable an improved measurement of the 1S-2S transition frequency by three orders of magnitude which is the aim of the ongoing Mu-MASS experiment.…”

Recent and ongoing developments of low energy muon beamlines are heralding a new era of precision Muonium spectroscopy. While past spectroscopic measurements of Muonium were performed at pulsed muon facilities and were statistically limited, the advent of continuous low energy muon beams, such as at the LEM beamline at PSI, paired with the development of efficient muon-muonium converters and laser advancements, will overcome these limitations. Current experiments presently underway at the LEM facility and in the near future at the muCool beamline, which is under development at PSI, aim to improve the precision of both the 1S-2S transition determination and Lamb shift by several orders of magnitude. In this Chapter we give an overview of the current status and future prospects of these activities at PSI, highlighting how their projected significance fits into a broader context of other ongoing efforts worldwide.

“…While many areas in research and industry have and continue to benefit from these sources [1][2][3], the lack of wavelength selectivity and frequency resolution limits research in atomic, molecular, and optical physics. For example, access to single photon Rydberg excitation [4], Rydberg dressing [5], tight optical lattices [6] and precise determination of physical constants [7] all require tunable, wattlevel, DUV laser light with application-specific wavelengths. The development of these laser sources is also crucial to the burgeoning field of direct molecular laser cooling [8,9] as several promising candidates possess strong optical transitions with high saturation intensities in the DUV, e.g., AlF, AlCl [10][11][12], leading to large recoil velocities and the potential for significant light-mediated forces.…”

We present a high-power tunable deep-ultraviolet (DUV) laser that uses two consecutive cavity enhanced doubling stages with LBO and CLBO crystals to produce the fourth harmonic of an amplified homebuilt external cavity diode laser. The system generates up to 2.75 W of 261.5 nm laser light with a ∼2 W stable steady-state output power and performs second harmonic generation in a largely unexplored high intensity regime in CLBO for continuous wave DUV light. We use this laser to perform fluorescence spectroscopy on the 1 Σ ← 1 Π transition in a cold, slow beam of AlCl molecules and probe the A 1 Π | ′ = 0, ′ = 1 state hyperfine structure for future laser cooling and trapping experiments. This work demonstrates that the production of tunable, watt-level DUV lasers is becoming routine for a variety of wavelength-specific applications in atomic, molecular and optical physics.
