Topag picosecond laser for high-precision material processing
With the Angis laser system, Topag offers an alternative, ultra-compact, robust and economical solution in the MW peak range for high-precision laser processes that is suitable for surface processing.
High-precision laser processes require MW peak powers with short picosecond pulses. With the current state of the art, this requires a complex and expensive laser design based on SESAM, modelocking and water cooling. With the Angis laser system, Topag now offers an alternative, ultra-compact, robust and economical solution in the MW peak range without compromising on performance compared to conventional mode-locked ps lasers. Angi's picosecond lasers are tailored to a wide range of applications with high precision requirements, such as micromachining (e.g. surface processing of silicon wafers or volume processing of displays), time-resolved spectroscopy or OPO pumping. Lithuanian laser manufacturer QS Lasers combines gain-switch and Q-switch technology to replace the standard design of mode-locked lasers.
The laser system consists of a single housing with integrated oscillator, amplifier and electronics. It is available with the fundamental at 1064 nm and optionally with the second and third harmonics. The main beam parameters are 100 µJ at 10 kHz with 50 ps pulse duration, which corresponds to a peak power of 2 MW. The energy stability is < 2% RMS at 1064 nm and M2 is < 1.2 and the laser operates in SLM. All these characteristics are fulfilled by a single housing with the dimensions 390 x 250 x 164 mm3.
