Monolithic focusing optics for single emitter diode lasers

April 16, 2012 // By Julien Happich
LIMO Lissotschenko Mikrooptik GmbH has developed micro-optics for 'true' blue, high-performance single emitter diode lasers.

The technology focuses the beam with precision on an area measuring approximately 40x40µm². Micro-optics technology is ideally suited for pumping solid-state crystals or for fiber coupling. The new devices have already been successfully deployed for energy-efficient solid-state crystal pumping within the scope of the project 'Integrated Green Efficient Laser' (IGEL), which the German Federal Ministry of Education and Research (BMBF) has funded with EUR 3.5 million. The term 'green laser' may be misleading for some: The actual light source is a blue laser diode, the wavelength of which is converted upwards within the crystal to produce a green laser beam. LIMO won't be playing the spectrum when it comes to potential users of blue light micro-optics.
