“…A deep UV solid-state laser engine using the neodymium:YAG (Nd:YAG) laser as the fundamental light source requires a tunable laser for wavelength conversion. 20,21 The necessity of another tunable laser would increase the complexity of the laser engine and/or reduce the conversion efficiency. Another deep UV solid laser based on a titanium:sapphire master oscillator and a set of BBO harmonic generators could cause a problem; ie, the 193 nm wavelength absorption by BBO crystals will affect the decay durability and the conversion efficiency of the system.…”

“…Although UV lasers are constantly improving, the regime below approximately 240 nm remains highly challenging. For example, recent advances using CLBO crystals to generate 2 W of stable power at 261 nm [35] cannot be directly applied due to the phasematching properties of CLBO, which has a Type-I SHG cutoff wavelength at ∼237 nm [36]. Instead beta-barium borate (BBO) crystals have to be used, which exhibit greater DUVinduced damage [37], and achieving such powers stably over significant timescales (> hours) has not currently been demonstrated.…”

We present a novel optimised design for a source of cold atomic cadmium, compatible withcontinuous operation and potentially quantum degenerate gas production. The design is based onspatially segmenting the first and second-stages of cooling with the the strong dipole-allowed 1S0-1P1transition at 229 nm and the 326 nm 1S0-3P1 intercombination transition, respectively. Cooling at229 nm operates on an effusive atomic beam and takes the form of a compact Zeeman slower (∼5 cm)and two-dimensional magneto-optical trap (MOT), both based on permanent magnets. This designallows for reduced interaction time with the photoionising 229 nm photons and produces a slowbeam of atoms that can be directly loaded into a three-dimensional MOT using the intercombinationtransition. The efficiency of the above process is estimated across a broad range of experimentallyfeasible parameters via use of a Monte Carlo simulation, with loading rates up to 108 atoms/s intothe 326 nm MOT possible with the oven at only 100 ◦C. The prospects for further cooling in a faroff-resonance optical-dipole trap and atomic launching in a moving optical lattice are also analysed,especially with reference to the deployment in a proposed dual-species cadmium-strontium atominterferometer.

“…We first present a model calculation using parameters from published experimental conditions to show and compare the relative effects of the pulse delay, input polarization, and orientation of the nonlinear crystals on the output power. Finally, since -BaB 2 O 4 (BBO) and CLBO nonlinear optical crystals are quite readily commercially available nowadays for deep UV generation, [20][21][22][23] we present a calculation using our model to compare the merits of using these two crystals for efficient fourth and fifth-harmonic generation (5HG) of a Q-switched diode-pumped Nd:YAG laser.…”

A model for the fifth-harmonic generation of pulsed IR lasers involving an external ring cavity resonating at the second harmonic has been developed. Numerical analysis is performed to show the relative effects of the pulse delay, input polarization, and orientation of the nonlinear crystals on the fifth harmonic power. The results are validated by published experimental results. The model is used to analyze and obtain the optimal combination of nonlinear optical crystals for the fifth-harmonic generation. Our calculation shows that the combination of LiB 3 O 5 (LBO), CsLiB 6 O 10 (CLBO), and CLBO crystals for the second-harmonic, fourth-harmonic, and fifth-harmonic generation steps respectively gives an approximate conversion of 30% from the fundamental to the fifth harmonic power, resulting in 2 W at 213 nm for an input of 7 W at 1064 nm.
