Historically, our High-Power series was the very first development by CryLaS. Depending on the model, repetition rates of 20 Hz to 100 Hz can be realized. Compared to the later developed Q lasers, these models have a slightly larger controller as well as a larger housing, but have much higher pulse energies. By frequency multiplying trough non-linear optics of the 1064 nm fundamental wave, it is possible to generate 4 additional laser wavelengths
- 213 nm
- 266 nm
- 355 nm
- 532 nm
A closed-loop control system internally monitors the stability of the laser. A photodiode measures the relative laser energy during emission. These data are processed and finally result in a temperature adjustment of the laser head, which is thus always kept at the thermal optimum. In this way, it counteracts heat generation, e.g. in the resonator. This results in low noise of the output power.
The advantage of the FDSS532 series of the High-Power lasers is, that only one conversion stage of the fundamental wave is needed to generate the 532 nm. After pumping the laser crystal with an 808 nm laser diode, the generated 1064 nm radiation is guided into an NLO crystal where it is frequency doubled and thus converted to 532 nm. Depending on the pumping time, laser energies of 150 µJ to 1 mJ can be generated. This is suitable for applications based on ablations, such as materials processing or laser-induced plasma spectroscopy LIBS on, for example, gemstones, which absorb the green laser light well. Photoacoustic applications are also possible.
