WaveTrain® 3D External Cavity Frequency Doubler For CW Lasers WaveTrain 3D 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 Matisse® series lasers, as well as to generate harmonics of the output from MixTrain and WaveTrain modules. Output stability is further enhanced by the use of a lightweight piezo-activated prism to optimize the cavity length, making the WaveTrain 3D especially resistant to vibrations and acoustic noise. This inherent beam stability enables the fully digital control hardware to automatically lock the cavity for maximum doubling efficiency during both fixed frequency and scanned operation. WaveTrain 3D utilizes a ring cavity to achieve efficiencies greater than 35%. Unlike conventional bow-tie cavities, WaveTrain 3D 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. Ease of access and the use of pre-mounted modular optics and crystals insure maximum wavelength flexibility, enabling the WaveTrain 3D to be operated effectively over the entire 412–1600 nm input wavelength range. • Input wavelength range 412 to 1600 nm • Fast servo loop ensures power stability • Continuous scans of 65 GHz at 10 GHz • Sealed cavity block and body with external adjustments prevent contamination of optics • Only two pre-mounted mirrors for quick change of wavelength ranges • Low cavity losses and high doubling efficiencies • Fully digital control electronics for ease of use andautomation • Atom cooling and magneto-optic trapping • Tunable UV experiments • Bose-Einstein condensates • Atomic cloc
