“…A least-squares fit to (1) yields L = 10(4)% for the parasitic loss in the bidirectional case. In [5] we found the loss in an empty four-mirror bow-tie cavity of mirrors from the same batch to be smaller than 1%. We attribute the remaining 9(4)% mainly to aberrations caused by the thermal lens in the Nd:YVO 4 .…”

“…To minimize detrimental thermal effects in the gain medium, the following pathway has been chosen: A pump wavelength of 888 nm in contrast to the former 808 nm [5] leads to a lower quantum defect per absorption-emission cycle [11], and thus to lower heating for a given pump rate. In addition, a larger value for the laser crystal length has been chosen in order to spread the heat input over a bigger volume.…”

“…Although this analysis essentially relies on plane waves, it can be mapped to the more realistic case of top-hat pump beams and gaussian laser cavity eigenmodes, as present in diode-pumped solid-state lasers, see [5] and references therein. A least-squares fit to (1) yields L = 10(4)% for the parasitic loss in the bidirectional case.…”

“…Second harmonic generation (SHG) is then established using periodically-poled potassium titanyl phosphate (ppKTP) as the nonlinear medium. The development of a number of related laser sources has been published recently [3,4,5], and the system developed in our group [5] has proven highly reliable in every-day operation over the period of one year. However, these sources are currently limited to output powers in the few-hundred-milliwatts regime.…”

Abstract:We present an all-solid-state laser source emitting up to 2.1 W of single-frequency light at 671 nm developed for laser cooling of lithium atoms. It is based on a diode-pumped, neodymium-doped orthovanadate (Nd:YVO 4 ) ring laser operating at 1342 nm. Optimization of the thermal management in the gain medium results in a maximum multi-frequency output power of 2.5 W at the fundamental wavelength. We develop a simple theory for the efficient implementation of intracavity second harmonic generation, and its application to our system allows us to obtain nonlinear conversion efficiencies of up to 88%. Single-mode operation and tuning is established by adding an etalon to the resonator. The second-harmonic wavelength can be tuned over 0.5 nm, and mode-hop-free scanning over more than 6 GHz is demonstrated, corresponding to around ten times the laser cavity free spectral range. The output frequency can be locked with respect to the lithium D-line transitions for atomic physics applications. Furthermore, we observe parametric Kerr-lens mode-locking when detuning the phase-matching temperature sufficiently far from the optimum value.

“…In previous works, single-longitudinal-mode lasers at 671 nm have been produced with the combination of a Nd:YVO 4 ring laser and a frequency doubler [6][7][8][9] . In these studies, unidirectional lasing was realized by placing an optical diode comprised of a terbium gallium garnet (TGG) crystal and half-wave plate inside the ring cavity.…”

We have constructed a solid-state light source for experiments with laser cooled lithium atoms based on a Nd:YVO 4 ring laser with second-harmonic generation. Unidirectional lasing, an improved mode selection, and a high output power of the ring laser was achieved by weak coupling to an external cavity which contained the lossy elements required for single frequency operation. Continuous frequency tuning is accomplished by controlling two PZTs in the internal and the external cavities simultaneously. The light source has been utilized to trap and cool fermionic lithium atoms into the quantum degenerate regime.

We present a highly stable bow-tie power enhancement cavity for critical second harmonic generation (SHG) into the UV using a Brewster-cut β-BaBO (BBO) nonlinear crystal. The cavity geometry is suitable for all UV wavelengths reachable with BBO and can be modified to accommodate anti-reflection coated crystals, extending its applicability to the entire wavelength range accessible with non-linear frequency conversion. The cavity is length-stabilized using a fast general purpose digital PI controller based on the open source STEMlab 125-14 (formerly Red Pitaya) system acting on a mirror mounted on a fast piezo actuator. We observe 130 h uninterrupted operation without decay in output power at 313 nm. The robustness of the system has been confirmed by exposing it to accelerations of up to 1 g with less than 10% in-lock output power variations. Furthermore, the cavity can withstand 30 min of acceleration exposure at a level of 3 g without substantial change in the SHG output power, demonstrating that the design is suitable for transportable setups.
