I have been working with an IR Raman 785nm system for about 2 1/2 years now. It was always frustrating not being able to see the beam except with a CCD camera. A few months back i started looking into this behavior and found a new material that up-converts the IR energy into visible range. Another interesting thing is takes IR and converts it to a series of Eigenvalue wavelengths, like 266, 351, 451, etc. Of course the output of each Eigenvalue drops by roughly 10 times. The photo attached is a 785nm IR laser impinging on this experimental anti-stokes device. Wearing safety glasses you can see the scatter at 451nm( royal blue), because the glasses only have about 0.1 OD at this frequency. I tested from 785 to 930nm and i believe this material to be a broadband converter maybe beyond 1064 and might go to 1500 range like the Erbium lasers. I sent 2 to Mr. Hug to test.
