PLENARY SPEECH by Fredrik Laurell "The Backward Wave Optical Parametric Oscillator"
Fredrik Laurell is a professor of physics at KTH, the Royal Institute of Technology. He is a Fellow of Optica and member of the Royal Swedish Academy of Engineering Sciences. He has been the chairman of the Swedish Optical Society, and the Swedish national committee for optics (ICO). He cofounded PhotonicSweden, the national platform in Photonics, and chaired the Optics section at the Royal Swedish Academy of Sciences and he work on leadership positions at EOS for more six years. He has authored or co-authored more than 300 scientific journal papers and 500 conference papers and he holds 18 patents. He has co-founded 5 companies and received the Göran Gustafsson Prize in Physics. Laurell’s research spans studies of optical materials, fiber optics, nonlinear optics, and laser physics. He is particularly interested in pushing photonics into real world applications and works extensively with outreach activities. | ||

|
In this talk I will present the backward optical parametric oscillator (BWOPO), a new nonlinear device which have some unique properties. It is a single chip, quasi-phase matched, nanodomain-engineered crystal which, when pumped with an intense laser beam, generates a narrow-linewidth, frequency-stable, contra-directional down-converted beam, and a collinear beam that inherits the spectrum of the pump. Compared to regular optical parametric oscillator the BWOPO provides a very narrow spectrum, easily tunable without mode hops and with a high conversion efficiency. It is among other things excellently suited for differential absorption lidar (DIAL) spectroscopy. I will describe the BWOPO properties in details and how it can be used. | ||
