We all know that blue laser diodes are widely used in daily life, so do you know where they are mainly used? Let's take a look at it together.

Laser projection and display

Blue light is one of the indispensable main light sources in laser projection, because it has a wide color gamut, sufficient energy, can be used as a high-power pumping source, and has strong color expression.

industrial process

The second largest application of blue light LD is industrial processing equipment, mainly because blue light has high absorption rate of metals (especially copper and gold).

The processing efficiency is much higher than that of infrared, the heat affected zone is small and the accuracy is higher.

Copper welding, metal precision welding

Lithium battery copper foil welding, metal foil welding, precision electronic welding

Blue light processing has become a hot technology in the manufacture of new energy batteries.

metal finishing

Include blue light cleaning, metal surface modification and micro-carving.

Blue light is very suitable for micro-machining because of its short wavelength and small focus.

Biological detection and scientific experiment

Blue light is also common in scientific research, especially at 405nm, because it can excite many fluorescent dyes.

Applications include: flow cytometry, fluorescence detector, biological sample excitation light source, microscopic imaging (fluorescence microscope), spectrometer excitation light.

The above is the main application of blue laser diode. I hope you will have a clear understanding after reading it.
