In the high-power diode laser industry, the available laser power from edge emitting facets has to be collimated for use in the many different applications.
This webinar will focus on the first lens after the diode laser facet, the fast axis collimator (FAC), formed as a circular lens. As examples micro-optic collimation is presented for two applications:
- Laser-spot formation for individually addressable laser bars for CTP printing
- Collimation for a high-power diode bar emitter developed for automotive LIDAR applications
Who Should Attend?
Professionals with roles in the development and application of laser technologies:
About the Presenter:
Martin Forrer has a master’s degree as Physicist from ETH Zurich and a PhD in medical laser applications from the University of Berne. He started his work in industry in 1997 on European projects to increase high power for diode lasers in the infrared. Since then he has realized various successful product developments up to the industrial scalability in micro-optics, endoscopic micro-camera vision and diode laser integration. After 13 years leading the FISBA R&D team he took a new challenge in 2019 as Senior VP Business Development.
Full Program Description:
In the high-power diode laser industry, the available laser power from edge emitting facets has to be collimated for use in the many different applications. Some variants for this collimation function do exist, industrially widespread is the use of glass material collimation micro-optics, separate for fast and slow axis of the laser emission. We will focus on the first lens after the diode laser facet, the fast axis collimator (FAC), formed as a circular lens.
Performance aspects for the optical collimation function and its application as a micro-optical assembly are presented. In view of the rising power levels available for high power blue diode laser emission we show results for FAC in fused silica material, as opposed to high refractive index glasses.
Fully automated variants for assembly of micro-optics on a bottom tab is done in a controlled active positioning mode relative to the facet of the Fabry-Perot cavity emission with up to 5 or 6 axis and with feedback from the laser light collimated by the refractive component. The FAC also is automatically characterized by an optical measurement in front of a specific diode laser source.
As examples micro-optic collimation is presented for two applications, laser-spot formation for individually addressable laser bars for CTP printing and collimation for a high-power diode bar emitter developed for automotive LIDAR applications.
