Picosecond Laser

High Q Laser Production (Hohenems, Austria) has introduced the mode locked picoTRAIN^TM 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 picoTRAIN^TM 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.
