Blue and Viloet Lasers
Until the late 1990s, when blue semiconductor lasers were developed, blue lasers were large and expensive ,and needed high currents and strong cooling.
Thanks to prior development of many scientist groups, the technology behind these gallium nitride lasers has allowed a series of inventions and developed commercially viable blue and violet semiconductor lasers.
These lasers are useful for applications such as biomedical instrumentation, imaging, spectroscopy, laser induced fluorescence sensing and microscopy. |

| Warning! These lasers emits radiation that can be harmful to the eye. Do not look directly into the laser aperture. Direct viewing of laser beam at close range may cause eye damage. (see laser classification) |
