1.5 Watt 405 nm Near-UV Laser Diode Pointer

Here's a nice host built by Lifetime17 which has a 405 nm laser diode in it being pushed hard to produce about 1.5 watts of output power. When pushed that hard, the wavelength is actually between about 410 to 412 nm which is not at all UV or ultraviolet, but many individuals refer to these diodes as UV.
