InnoProfile - Initiative

Hybrid Diode Laser Systems - Berlin

The InnoProfile junior research group, headed by Dr. Katrin Paschke, develops powerful highly brilliant hybrid laser sources using micro optics and crystals.

All work is executed in close co-ordination with regional small and medium-sized enterprises, which are not only informed about results but also contribute with their market knowledge. This approach also sustainably strengthens the innovative and economic power of optical technologies in the Berlin and Brandenburg region.

Partial projects:

• Development of semiconductor structures and optimization of chip technology
  • Semiconductor structures in the near infrared (NIR) spectral range with extremely low divergence
  • Structures for semiconductor lasers for 635 nm and 660 nm
  • Internal Bragg reflectors for wavelength stabilization

• Design and realization of highly brilliant laser systems with optical output powers of more than 10 W in the NIR spectral range for frequency conversion

• High-precision mounting of semiconductor devices and optics on micro-optical bench
  • Design of a miniaturized laser module in the visible spectral range with integrated second harmonic generation
  • Further development of the processes for positioning in the sub-micrometer range
  • Optimization of the heat management system of active and passive elements

• Design, realization and optimization of laser systems for the visible spectral range for cw as well as for pulsed laser operation

The BMBF initiative is funded with 3 Million Euro since January 2007 over a period of five years. For investments, another 1.4 Million Euro were granted by the BMBF in June 2008. This funding will be used in wafer technology, in mounting and assembling as well as for further equipment in device characterization.
