FREIBURG, Germany, April 19, 2011 — In cooperation with partners Xiton Photonics and the Institute for Medical Laser Technologies of Ulm University, Z-Laser Optoelektronik GmbH has developed a blue 457-nm-emitting laser module based on solid-state disk laser technology. With beam quality of M2 1.0 and optical power of >500 mW, the module measures 300 × 200 × 200 mm. Highly efficient pumping of the solid-state disk was achieved via an 880-nm-emitting laser bar. Bulky thermal masses were eliminated with this approach, without affecting the performance of the laser. The air circulation-based cooling mechanism works without water or costly and cumbersome equipment, so the laser can be used in the laboratory as well as in industrial and medical fields. Included are the optical system, the air cooling ventilation, the electronics and the user interface. The system can be fully customized for OEM clients, and the optical head, including the disk and pumping resonator, are offered for integration into a customized system.
