Knowledge of Blue Laser Diodes

The blue laser diode is a semiconductor laser device that can emit blue light. Its wavelength is usually 405nm/450nm/488nm, and 450nm is the most common. Compared with other lasers, the blue laser diode has the widest power range. If you need a powerful laser, the 450nm blue laser is recommended.

Medium/low-power blue lasers can be used for stage lighting, laser sights, optical experiments, biological detections, etc. High-power blue laser diodes are widely used for engraving, cutting, welding, weapon parts, etc.
