OYAT, the quasi-continuous fiber laser, delivers high power and high frequency picosecond pulses.
Its innovative patented fiber design enables high power, high pulse repetition rate, picosecond pulses all in a single
mode-beam in the UV at 343 nm.
The fiber technology combined with the simply efficient laser head architecture makes OYAT a robust, and costperformance visible QCW laser for most demanding industrial applications. Manufactured with a field proventechnology, qualified components and good practices, BLOOM lasers are the right answer to 24/7 operations inextended production cycle environments.
