Our resonators are successfully employed in a diversity of experiments around the globe. In the following we provide some references.

1.84 W in the UV
SHG cavities for 522 nm and 261 nm generation
The group of Daniel McCarron from the University of Connecticut set up two consecutive SHG cavities to produce up to 1.84 Watts of cw light at 261 nm by frequency-quadrupling the output light from a fiber laser system. The resonator housings for both doubling steps (1044 nm to 522 nm and 522 nm to 261 nm) were custom built by Agile Optic GmbH for this application.

UV cavity 280 nm
SHG cavities for 560 nm and 280 nm generation
"Since 2003, our group develops new tools and methods for quantum simulation research based on trapped atomic ions (https://www.qsim.uni-freiburg.de). Robust laser systems delivering light near 280 nm with output powers between 0.1 to 0.5 W are key in our work.

423 nm Cavity Application
SHG cavity for 423 nm generation
The group of Prof. Dr. Andreas Hemmerich from the University of Hamburg set up a SHG cavity that generates more than 800 mW of cw light at 423 nm from a diode laser at 845 nm that is amplified in a TA system. The resonator used is one of Agile Optic´s standard products.

650 nm Cavity
650 nm for quantum frequency conversion
"We envision a future quantum computer to be hybrid device that comprises both cold atom/ion and solid state qubits. Quantum frequency conversion is required to interconnect these platforms. Within the German Cluster of Excellence ML4Q, we set up the link between GaAs quantum dots (around 850 nm) and Yb+ ions (370 nm) by employing sum frequency generation in PPKTP crystals. The required pump light has a wavelength of about 650 nm. A few 100 mW are required to saturate the nonlinear conversion process, and the light needs to be tunable by about 30 nm to match the variable emission wavelength of the quantum dot. These two criteria cannot be fulfilled by a single diode laser, nor by single-pass SHG in a waveguide or bulk crystal. Here, we employ an amplified diode laser combined with an SHG cavity to generate broadly tunable and powerful light around 650 nm."
