All you need to know about  NUBM44/47 Nichia laser diodes

A NUBM44 is a 445nm laser diode that emits 6-7 watts of optical power on the average in a CW mode. At the moment it is the highest power laser diode in a 9 mm TO-5 mount. A NUBM44 is specified with a typical center wavelength of 445 nm (dark blue). This is a multi-mode laser diode, it has a pretty narrow waveguide, which allows it to have nearly the lowest etendue (far-field divergence for a given beam diameter) of any high-power semiconductor laser. The narrow emitter width enables to better collimate and focus it than other high-power laser diodes. This is a big advantage of this unit.

This laser has a chemical formula of GaN. The laser operates at temperatures up to 60-65C without significant power or lifetime loss. But the colder the laser – the better. But if the temperature exceeds 70-80C the diode can dramatically lose its power before final degradation. The temperature shift to colder parameters will decrease the laser wavelength.

General datasheet about NUBM44

  • Gallium Nitride (GaN) blue laser diode
  • 6-7-watt blue laser,
  • 445 nm wavelength;
  • easy to focus and collimate with G2, G7, G8 lens;
  • a compact TO-5 (9mm) mount;
  • a wide range of operating temperatures (0C to 65C);
  • a longer lifetime at higher operating temperatures due to GaN.
