Feb 2014
ROSKILDE, Denmark, Feb. 19, 2014 — The Technical University of Denmark (DTU) has branched out with the formation of Norlase, a new company specializing in a unique class of visible lasers.

The diode lasers are based on technology from DTU. Norlase frequency-doubles the tapered diode laser with a nonlinear crystal, utilizing the stability of semiconductor lasers with levels of output power typically associated with optical pumping.

Norlase laser technology provides designers of OEM equipment with stable, low-noise, compact, visible lasers in the 1- to 20-W CW range. It performs in a variety of applications, including DNA sequencing, dermatology treatments, laser projection displays and laser spectroscopy.

The company was founded by CEO Peter Skovgaard and board chairman David Hardwick. Skovgaard has more than 20 years of experience in the photonics industry, and in the past has worked at companies such as NKT Photonics and Kalieido Technologies. Hardwick is a 50-year industry veteran with experience at companies including IPG, Melles Griot and Spectra Physics.

GLOSSARY
optical pumping
The process whereby the number of atoms or atomic systems in a set of energy levels is changed by the absorption of light that falls on the material. This process raises the atoms to specific higher energy levels and may result in a population inversion between certain intermediate levels. The optical pumping of an optical medium within a laser cavity is one of the fundamental processes involved in the generation of a beam.
