Blue Diode Lasers (blue semiconductor lasers), which are typically fabricated out of aluminum gallium nitride (AlGaN) or aluminum indium gallium nitride (AlInGaN), are one of the newest laser diodes available on the market today, having been first demonstrated in the mid-1990s. Over the past 20 years, blue diode lasers have found uses in a wide variety of applications, most ranging from RGB laser displays to aesthetic lasers for acne treatment. High power blue laser diodes provide void-free, spatter-free welds on copper, non-ferrous metals, and dissimilar metals. In addition to blue diode lasers, diode-pumped solid-state (DPSS) lasers are also available offering extremely long coherence lengths for applications such as Interferometry, Holography, and LIBS. DPSS lasers can produce blue laser light through harmonic generation (3rd harmonic / frequency-tripling) of neodymium-doped yttrium lithium fluoride (Nd:YLF) gain media.
Blue laser light is efficiently absorbed by most metals. Considering this, blue wavelength lasers can be an extremely versatile tool, able to process most materials.
