GONZALEZ, Juan Eduardo; RIOS, Luis Antonio; YANKELEVICH, Diego Rubén  e  CUDNEY, Roger Sean. Efficient conversion from infrared to red light by cascaded nonlinear optical processes using an aperiodically poled lithium niobate crystal. J. appl. res. technol [online]. 2015, vol.13, n.6, pp.582-585. ISSN 2448-6736.  https://doi.org/10.1016/j.jart.2015.10.011.

We present a scheme for conversion of pulsed light from the infrared to the red spectral region, using an aperiodically poled ferroelectric crystal within a resonant cavity in which two cascaded nonlinear optical processes occur when pumped with a pulsed Nd:YAG laser. This device emits 9 ns pulses of over 1 mJ at 710 nm and is a viable source for future biomedical applications.
