Tapered semiconductor diode lasers have matured over the past 15 years from a university research topic to a commercially viable technology. Our laser systems are based on stabilized, frequency-doubled, tapered diode lasers. Our core technology builds on published research at the Technical University of Denmark (see, for example, Jensen et al, Optics Letters, 2012). It eliminates the troublesome cavity of traditional visible lasers, such as DPSSL and OPSL. Our patented, simple laser architecture enables high-quality lasers, in an extremely compact and uncooled format. Norlase is able to achieve wavelengths typically out of reach to traditional laser technologies and presently target AuroraOne lasers in the 515 – 577 nm range.
The AuroraOne offers advantages in multiple applications, including OCT (Optical Coherence Tomography). The OCT performance improvement from using the AuroraOne low noise tapered diode technology was demonstrated by the Technical University of Denmark in collaboration with Medical University of Vienna, Bern University of Applied Sciences, EXALOS, and Femtolasers (Unterhuber et al., Optics Letters, 2013). The pictures show a direct comparison between OCT of a human retina using a Norlase-based OCT system (top) vs. a market-leading system based on traditional pump lasers (bottom). The improved noise performance results in significantly improved contrast of the OCT image, enabling faster and more reliable diagnosis of diabetes, AMD, cataracts and more.
