GWU Lasertechnik Vertriebsges.mbH is specialized on developing and manufacturing non-linear optical systems like OPOs based  on BBO, LBO, and KTP.  In  1989  GWU introduced the  first  commercial  OPO of BBO  worldwide.  The applications  for  GWU´s   OPOs include   medicine,  material  research,  environmental   analysis,  and  spectroscopy. Currently  GWU OPOs cover the spectral range from  200 nm  to  >4.5 mm.   Besides OPOs GWU offers harmonic generators (doublers, triplers, quadruplers, and mixers) and differnt pulsed and CW lasers.

GWU Lasertechnik Vertriebsges.mbH  acts  as  agent  for  Fujian  CASTECH crystals - the inventors  of BBO and LBO crystals - and for HC Photonics - high quality QPM devices and green lasers.  Because of this relationship  GWU Lasertechnik Vertriebsges.mbH  could  offer  a  wide range of crystals and other optical materials.

Since 2005 GWU Lasertechnik is also distributing "Spectrelle" - echelle spectrographs and Xiton Photonics DPSS lasers.

At Laser Munich 2007 GWU announced their cooperation with NP Photonics offering ultra-stable low noise fiber lasers and ASE sources. 

GWU offers customized solutions and participates in research projects.

Quality is one of the major company guidelines. GWU is certified to ISO 9001.
