An integrating sphere is a powerful tool to capture all the light of a widely divergent beam. The sphere scatters light uniformly over its whole interior.

Read this before before you do any damage.
Technically, silicon absorbs well down to 350 nm, and could even work at lower wavelengths (to 190 nm).
However,

You can now measure your laser directly from the Ethernet network, without any need to go through to a PC.
Ophir’s new EA-1 is an Ethernet Adapter which can be used with virtually all power sensors to turn them into an Ethernet laser power meter.

“You can do Profinet, right?”
John had just ordered 10 laser welding stations for his new car manufacturing facility. As a laser system integrator, you talked to him in detail about all the specs. What exactly does he need from the laser? What sort of control equipment does he have? What else does he need?
John added, almost as an afterthought – “The facility is in Germany, so of course we want all the lasers and devices running on Profinet. You can do that, right?”
Uh-oh.
