Or use angle-polished fiber.
With photodiodes, sure--hit the window with a ball-peen hammer, very gently. Works great. I've never done that with lasers, though. The hermetic-package ones may or may not be passivated, and if not, they'll croak over pretty rapidly. Also the facet attracts crud photophoretically, so it gunks up rapidly unless it's in a well-sealed package of some sort.
Also the windows on DL packages are generally smaller than on photodiodes.

Thanks Joe, I've got zero 'formal' optics training. Scheimpflug is bit of a mouth full, is the p pronounced?

Works great at least with 5.6mm DLs, but sometimes requires enough force to bend the case a little bit so that the hammer reaches the glass.
The photophoresis sounds interesting, I think I have to try that!
