HL40161MG & HL40163MG 405nm blue-violet laser diodes


Ushio’s new HL40161MG & HL40163MG 405nm blue-violet lasers work in record temperature range; from freezing to near-boiling

NEWS: December 2022

Ushio has announced the development of two new 405nm laser diodes that have broken the operating temperature range records for 405nm laser diodes.

Achieved through advanced crystal growth technology and a unique optical confinement control structure, Ushio’s HL40161MG & HL40163MG violet-blue laser diodes function in extreme temperatures between -5℃ and +85℃. In addition, both lasers boast a high light flux density over the entire temperature range and succeed in achieving stable, uniform beam characteristics with a low aspect ratio.

The HL40163MG blue-violet laser diode will enter mass production in the first quarter of 2023. The HL40161MG is expected to enter mass production in the second quarter of 2023 and will feature a built-in photodiode in addition to the blue-violet light source found in HL40163MG.

Industries expected to adopt HL40161MG & HL40163MG violet-blue laser diodes.

We anticipate these laser diodes  will be welcomed by a wide range of industries where stable performance is required in various environments. These industries include industrial sensors, medical equipment, measuring and analysis equipment, 3D scanners and 3D printers.

Ushio is expanding its line-up of blue-violet laser diodes and has committed to the spread and performance improvement of blue-violet laser diode-equipped devices in an even wider range of applications.

How and why are 405nm blue-violet laser diodes used?

405nm single-mode laser diodes are the light source used for reading Blu-ray discs.  However, in recent years, their applications have expanded to encompass industrial sensors, medical equipment and measuring instruments.

In particular, for applications such as particle detection in semiconductor processes and 3D scanners for inspecting electronic components and substrates, there has been an increasing need for finer particle detection and higher resolution inspection which requires illumination with high light flux density and uniformity. For these applications shorter wavelengths reduce the focused spot diameter so high-power lasers with stable beam quality over a wider range of temperature conditions are required.

HL40163MG and HL40161MG 405nm features:

  • Optical output power and wavelength: 175mW, 405nm (Tc=25℃)
  • High temperature operation: Max operating temperature +85℃
  • Superior beam quality: Adopting unique optical confinement control structure
