7W+ 450nm NUBM44-81/NUBM47-A1 Laser Diode

7W NUBM44-V2(NUBM44-81/NUBM47-A1) 450nm Laser Diode 

This is currently the most powerful known visible wavelength diode

UPDATE 6W NUBM44-71/NUBM47T the original version of this diode has been out of production for a few years now. 

The new 7W NUBM44-V2 diodes are the 7W NUBM44-81/NUBM47-A1. The NUBM44 vs NUBM47 refer to the number of NUBM44-V2 diodes in the block. 

The NUBM44 diode blocks have 8 diodes vs the NUBM47 diode blocks which have 10 diodes.  Both blocks contain the same 7W NUBM44-V2 diodes.

There is some confusion that the power difference is 44 vs 47 but it is 6W NUBM44 out of the NUBM44-71/NUBM47T vs 7W NUBM44-V2 out of the NUBM44-81/NUBM47-A1.
