Nonlinear Optical Consulting

Nonlinear optics technology has the capability to create new wavelengths from standard laser technology. For example, use of a KTP crystal in an optical parametric oscillator based on a Nd:YAG laser can create wavelengths between 1570 nm and 3300 nm. These wavelengths can extend the applicability of well established lasers and create new markets. Of course, frequency conversion is not limited to Nd:YAG -- nonlinear techniques can be used to create wavelengths anywhere from short ultraviolet to deep infrared. Applications for these new wavelengths include medical lasers, remote sensing, textile manufacturing, chemical engineering, spectroscopy, and computer manufacturing.

Fortunately, the cost of nonlinear optical materials is decreasing. Unfortunately, the implementation of these devices is rather complicated. Proper design and optimization of nonlinear devices requires a highly trained engineering staff. Our consulting service was founded to help laser companies who don't have access to such engineers. We can assist with the entire range of the design process -- from basic research to assembly line tooling. Our services are available at any level to complement your in-house capability and bring new products to market. Contact us by phone (757-865-8073), fax (757-865-4447) or e-mail (met@gc.net) to see if nonlinear devices can help with your application.

Example of Nonlinear Calculation

The following graph gives angular bandwidth data for the nonlinear interaction of Sum Frequency Generation of 355 nanometer light with a 1556 nm pump beam. This nonlinear interaction is classified as type II tangential phasematched interaction. The mixing takes place in a Beta Barium Borate (BBO) nonlinear crystal. This data is real and shows the dramatically large angular acceptance of the 1556 nm light beam compared to the 355 nm light beam. Data like this allows engineers to make intelligent choices in the design of nonlinear frequency conversion schemes.

The software that generated this data is written in MathCAD 6.0+ and is quite flexible in determining other parameters effecting nonlinear conversions processes. The software is not for sale but our time is. Please give us a call and we will see if nonlinear processes can help you meet your goals.
