WaveTrain 3D Patented Cavity Design

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.

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.

WaveTrain 3D Stability

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.

Maximum Wavelength Flexibility

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.

Digital Control Electronics with Touchscreen and GUI Interface

WaveTrain 3D features fully redesigned digital control electronics with a touchscreen and optional GUI interface. The platform is ready for integration into the most demanding scientific and industrial applications that require automation and computer control of laser equipment.

Compatible Power Sensors

To verify and analyze the output power of your WaveTrain 3D laser, we recommend the Ophir thermal power sensor (contact sales-selection depends on application) and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the website.  Other Ophir sensors and meters may also be suitable for the WaveTrain 3D, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
