Bending a laser beam's cross section possible?

Click For Summary
SUMMARY

Bending a laser beam's cross section is achievable using holographic gratings, which can transform the linear cross section of a diode bar into various shapes such as semi-circles or V formations. This method is commonly utilized in inexpensive laser pointers that include a set of holographic gratings for creating diverse patterns. The discussion highlights the practicality of using these gratings for manipulating laser beam shapes without the need for complex setups or specialized equipment.

So here's a crazy question...I was trying to think it through and have come up with nothing.

Is it possible to bend a laser beam's cross section? For instance, if you are using a diode bar (which has a beam cross section resembling a line) is there a simple way to bend it into a semi-circle, or V, or some other shape?

I don't actually have an immediate application for this in mind, I just happen to have a diode bar to play with...

Yes, the easiest way is a holographic grating.
Cheap laser pointers normally come with a set of them that gives you lines or crosses or even more complicated shapes.
 
Thanks! I will look into holographic gratings.
