22 Aug 2007 High Q Laser Production GmbH introduces the mode locked picosecond laser picoTRAIN Green IC-532-12000 - delivering 12 W @ 532 nm with synchronized and simultaneous output beams at 532 nm and 1064 nm.
Hohenems / Bregenz, Austria. May, 2007 High Q Laser now is introducing a high power picosecond oscillator - picoTRAINTM Green IC-532-12000 - with integrated second harmonic generation (SHG) delivering 20 W at a wavelength of 1064 nm and 12 W 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 high grade BBO crystal. The temperature control of the BBO crystal is achieved by a Peltier element controlled by the laser driver. The laser offers two separate output ports for 532 nm and 1064 nm. 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 4 W, 6 W and 8 W at 532 nm respectively for cost sensitive applications.
The picoTRAINTM Green IC-532-12000 is based on High Q Lasers proven IC platform. IC means Industrial Compatible. The IC platform features a very compact design and small footprint of only 630 mm x 200 mm x 80 mm (l x w x h) facilitating system integration of OEM customers. High Q Laser utilizes the URDM (User Replaceable Diode Module) technology for Direct Diode Pumping, enabling the customer for a quick and simple exchange of the pump laser diodes after their end of life of typical 10,000 hours. The IC platform is machined from a massive piece of aluminium and is forming a Monolithic Aluminium case leading to low vibration coupling. The laser resonator is supported by industrial mirror mounts, which are optimized by finite element method and show zero degrees of freedom. A recirculation cooling circuit through the massive ground plate and through the URDM is giving thermal stabilization of the IC platform. Optionally the IC platform is available with air cooling for low laser power levels. The monolithic housing is manufactured in a class 1000 clean room and is sealed off for longest hands-free operation. All those measure ensure an exceptional spatial and temporal stability of the laser output beam.
Customer Benefits:
Furthermore the customer benefits from the user friendliness and the true turnkey behavior of the picoTRAINTM Green IC-532-12000. The system offers an easy operation with a single phase power supply and is including a recirculation chiller. All functions of the laser system can be remote controlled and all relevant parameters can be acquired from the system via a serial interface which is important for commercial system integrators. The Direct Diode Pumping of the picoTRAINTM Green IC-532-12000 and the use of BBO as SHG crystal leads to low maintenance cost.

Applications:
The perfect temporal and spatial overlap of 532 nm and 1064nm pulse trains makes the system especially suitable for
Pumping of Optical Parametric Oscillators: such as the LEVANTE EMERALD OPO, the picoTRAINTM Green can pump up to two LEVANTE EMERALDs and by that providing up to six synchronized pulse trains at different wavelengths (e.g. 532 nm and 1064 nm, 690 nm to 990 nm with signal and 1150 nm to 2300 nm with idler of OPO 1 and 2)
Ultrafast spectroscopy: E.g. two-color pump-probe experiments with high spectral resolution in the ps-time domain, four-wave-mixing, multi-color pump-probe experiments
Multi-photon imaging: CARS microscopy, Two-photon-absorption-microscopy, SHG microscopy
Nano-Processing: Creating structures of nano- and micro-scale size by laser ablation.
