The Nd:YAG DPSS laser modules of our DPL and DPT series work at 1064nm or 532nm with a power up to 100mW and deliver beams with a high quality and polarisation (>100:1). Modules of  DPT series are furthermore active power and temperature stabilized. The show a very high power stability and low noise (< 0,5%). All modules are available with a variety of options as separate TTL-input (up tp 1MHz), a line or crossline optic, fiber coupling and homogeneous line generation. The applications are wide spread:  measurement, biotechnology, chemical analytics and  fluorescence-excitation .
