Violet Lasers Overview
Violet diode lasers have exploded in popularity over the past few years as the price of 405nm lasers have rapidly decreased in price and increased in power. Ironically depending on the application (and industry) 405 nm lasers are rarely acutely referred to as violet lasers, but instead, are commonly referred to as either blue, UV, or purple lasers. The most obvious example of this is in Blu-ray players where 405 nm lasers are used to read out the information stored on the disk. In addition to high-density optical storage, these laser diodes are used in a wide range of other applications from confocal fluorescence excitation to laser disinfection. Violet or Purple lasers are available with both single-mode and multi-mode beam profiles, and with either free space or fiber coupled outputs. OEM diode laser packages and CW laser modules are both available.
