* 405&nbsp;nm: [[InGaN]] blue-violet laser, in [[Blu-ray Disc]] and [[HD DVD]] drives
* 445–465&nbsp;nm: [[InGaN]] blue laser multimode diode for use in mercury-free high-brightness [[data projector]]s
* 488&nbsp;nm: [[InGaN]] green-blue laser; became widely available in mid-2018.
* 505&nbsp;nm: [[InGaN]] bluish-green laser; also became widely available in mid-2018.
* 510–525&nbsp;nm: [[InGaN]] green diodes developed by [[Nichia]] and [[OSRAM]] for laser projectors.<ref>{{cite journal | date=2016 | journal= Journal of Semiconductors | title=GaN-based green laser diodes | author= Lingrong Jian |display-authors=et al. |volume=37 | issue=11 | page= 111001 | doi= 10.1088/1674-4926/37/11/111001 | bibcode= 2016JSemi..37k1001L | s2cid= 114572097 | url=http://www.jos.ac.cn/article/id/aa00c3e5-f845-41a6-be34-d31ecd3944a3| url-access=subscription }}</ref>
* 635&nbsp;nm: [[AlGaInP]] better red-laser pointers, same power subjectively twice as bright as 650&nbsp;nm
* 650–660&nbsp;nm: [[Indium gallium phosphide|GaInP]]/[[AlGaInP]] [[Compact disc|CD]] and [[DVD]] drives, cheap red [[laser pointer]]s
* 670&nbsp;nm: [[AlGaInP]] bar-code readers, first diode-laser pointers (now obsolete, replaced by brighter 650&nbsp;nm and 671&nbsp;nm DPSS)
