Frequency doubler WaveTrain® 2

WaveTrain® 2 is an advanced stand-alone device that provides simple frequency doubling of single frequency CW laser beams. With greater efficiency than traditional intra-cavity or extra-cavity methods, this product can be used to generate the second harmonic of the output of the Matisse® 2. • Input wavelength range 410 to 1600 nm • Only two pre-mounted mirrors for quick change of wavelength ranges • Low cavity losses and high doubling efficiencies >35% Applications • Quantum Physics • Atom cooling • Magneto-optic trapping • Bose-Einstein condensates • Atomic clocks • High-resolution UV spectroscopy • Tunable UV experiments Patented DeltaConcept® Ring Cavity Design WaveTrain 2 utilizes a ring cavity to achieve efficiencies greater than 35%. Unlike conventional bow-tie cavities, WaveTrain 2 is based on a patented triangle-shaped cavity configuration called the DeltaConcept®, which allows the cavity length to be adjusted with no effect whatsoever on output beam position, direction or beam astigmatism. The DeltaConcept design requires two cavity mirrors (as opposed to four in a bowtie resonator) which minimizes losses for maximum output power. WaveTrain 2 Stability • Hermetically Sealed Resonant Ring Cavity for Crystal Longevity: The WaveTrain 2 resonant ring cavity is housed in a massive metal block and hermetically sealed with an O-ring and metal cover plate. Hygroscopic material inside of the housing protects against humidity. The doubling crystal is temperature stabilized and nitrogen purging is available.
