altHigh Q Laser Production (Hohenems, Austria) has introduced the mode locked picoTRAINTM Green IC-532-12000, a picosecond laser featuring integrated second harmonic generation (SHG) delivering 20W at a wavelength of 1064 nm and 12W at 532 nm in a 76 MHz pulse train with 6 ps pulses. The SHG is performed in a separate module via non-critical phase matching with a BBO crystal. The temperature control of the BBO crystal is achieved by a Peltier element controlled by the laser driver. The power distribution of 532 nm to 1064 nm radiation can be controlled continuously by a variable beam splitter. The TEM00 laser beam displays a beam quality of M2 < 1.2. Both the 532 nm and the 1064 nm pulse train are temporally synchronized. The picoTRAINTM Green is also available at different power levels of 4W, 6W, and 8W at 532nm. The system is suitable for pumping of optical parametric oscillators, ultrafast spectroscopy, multi-photo imaging, and nano-processing.
