PCI Express M.2 specification-Revision 0.7, Version 1.0,November 27, 2012, The M.2M.2 form factor is used for Mobile Add-In cards. The M.2 is a natural transition from the Mini Card and Half-Mini Card to a smaller form factor in both size and volume
Based on the theory of semiconductor laser pattern and the non-paraxial vectorial moment theory of light beam propagation, the beam quality factor M^(2) of TE_(0) propagating mode is analyzed and calculated. The result shows that when both core layer
