NUBM44 is a 445 nm, 6 W laser diode. This is the highest power diode currently available. In comparison, other laser diodes at 445 nm and 450 nm have a lower specified optical power. Examples are the Osram PLTB450B (1.6 W) and PLPT9 450C (3.0 W). Note that NUBM44 is also considered a 450 nm laser diode, and the two wavelengths are often used interchangeably to describe it.
