You need to find out the wavelength of the laser. Once you know the wavelength you can design a reflective shell around the projectile. Certain ceramics with proper coating are really good in scattering energy and are extremely resistant to heat.

That sounds impractical. Either you're trying to coat shells on demand in wartime, or stocking extra quantities targeted to this or that wavelength. If you're already stocking extra ammunition, it sounds better to just overwhelm the defensive system with more shells, like another commenter suggested.

If you're going to design something new, maybe something more like a MIRV launcher that fires three shells in the time it currently takes to fire one.

It's likely that your opponent is fielding only a limited number of laser projectile countermeasure systems, and also likely that they are related and only using a limited number of wavelengths.

But yeah, just throw a bunch of things and swamp their targeting systems.
