This is probably a dumb idea that won't work, but here goes.
It is a well-known fact that DPSS lasers have beam specs that are very different than that of their pump diode. This is because the diode is merely pumping the crystal, which generates a well-collimated laser beam.
I'm wondering if it's possible to use a similar setup to get a single-mode beam out of a multi-mode diode by using DPSS optics (pump focusing, expanding and collimating lenses) and some sort of crystal. Of course, the crystal would have to be able to output a beam whose wavelength and optical power is similar to the original diode.
Has anyone ever tried something like this?
