M Type laser Driver

[TravisRyno]

Can anyone explain to me what an M type diode driver is?

Here is a description of what I ordered:

M type Common cathode pin Constant power APC driver board laser diode drive.
Can drive RLD65MPT3, RLD65MPT4 T5 T7, 650nm 5mw 10mw 20mw Input Voltage 3-5V......
.....M 405nm 5MW 10MW 20MW 35MW 65MW 100MW input voltage


...And what is the "M" before 405nm on the last line for?

Thank you.
