A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...

A beamsplitter is an optical device capable of splitting an incident light beam into two. These tools can split both laser and regular light. A beamsplitter can also combine two incoming beams from ...

Data from a recent integrated ground test of the Alpha high-energy laser, its beam director telescope and the associated beam alignment and correction system have provided the team developing the ...

When the green laser encounters atoms along its path through the crystal, it gives the electrons in those atoms a bit of extra energy. In their high-energy state, those electrons can absorb blue light ...
