Title: Bjorn Hansson: Innovator in Laser Technology

Introduction

Bjorn Hansson is a notable inventor based in Vallentuna, Sweden. He has made significant contributions to the field of laser technology, particularly with his innovative designs and patents. His work has implications for various applications in both industrial and scientific settings.

Latest Patents

Hansson holds a patent for a Q-switched laser, which is powered by at least one pump source and is designed to provide pulses. The laser features two mirrors that create a laser cavity, housing a gain medium, a saturable absorber, and a controllable active modulator. The modulator can introduce loss through a control device. In the first phase of operation, the control device increases loss in the active modulator, setting a threshold inversion density band to a level high enough to exceed the actual inversion density in the gain medium. In the second phase, the control device rapidly lowers this loss, which in turn reduces the threshold inversion density band to a level lower than the actual inversion density, thereby activating the emission of the Q-switched pulse.
