07 September 2009 Frequency Conversion in BIBO

Single-pass conversion of picosecond pulses into the blue with BiB3O6

Prof. Majid Ebrahim-Zadeh reviews the recent advances on the nonlinear crystal BIBO. “Femtosecond nonlinear frequency conversion based on BiB3O6” is the title of the invited review published in Laser & Photonics Review (LPR) by ICFO Prof. Majid Ebrahim-Zadeh and Prof. Valentin Petrov (at Max-Born Institute, Germany), together with other collaborators. This comprehensive review summarizes the large volume of work performed by the authors on the nonlinear crystal BIBO over the past 5 years. The paper, now online, will be available in printed format later in 2009.

The review addresses the physical properties, linear and nonlinear optical characteristics, and phase-matching configurations of BiB3O6 (BIBO), the first low-symmetry (monoclinic) inorganic nonlinear crystal that has found broad applications for wavelength conversion. Frequency mixing with BIBO has been applied to laser sources from the UV, across the visible, to the near-IR, based on three-wave interactions. The article describes in detail the most relevant optical properties that make this material an attractive candidate for nonlinear frequency conversion of laser light in general, and ultrafast femtosecond laser sources and parametric devices in particular.
