WaveTrain® 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 tunable visible radiation from tunable CW Ti:sapphire sources or dye lasers or diode lasers. It can also produce CW laser radiation in the deep UV by doubling the output of ion lasers or all solid state green lasers.
WaveTrain utilizes a ring cavity to achieve efficiencies greater than 12%. Unlike conventional bow-tie cavities, WaveTrain 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.
Output stability is further enhanced by the use of a lightweight piezoactivated prism to optimize the cavity length, making the WaveTrain especially resistant to vibrations and acoustic noise. This inherent beam stability enables the control hardware to automatically lock the cavity for maximum doubling efficiency during both fixed frequency and scanned operation.
In addition, short DeltaConcept cavity length leads to large free spectral range (FSR), which allows pump lasers with larger frequency jitter to be frequency doubled with good stability. Ease of access and the use of pre-mounted modular optics and crystals ensure maximum wavelength flexibility, enabling WaveTrain to operate efficiently over the entire 410-1600 nm input wavelength range.
