    Photonic West – MARCH 2021

    Narrow linewidth laser diodes (LDs) emitting in the near-UV (NUV) are gaining attention for applications ranging from spectroscopy to atom cooling and interferometry or other applications requiring high spectral purity…

  • Post-treatment of dbr fibre lasers for enhanced beat-frequency in dual-polarization operation

    M. Guionie, M. Brunel, G. Loas (FOTON Institut); E. Pinsard, L. Lablonde, B Cadier iXblue


    UV photo-ablation provides an efficient and reproducible means to control the birefringence of a dual-frequency DBR fiber laser. The resulting beat note can be finely tuned by real-time measurement during the process from typically 100 MHz to about 6 GHz, independently of the active medium length.

    Research Gate

    The first InGaN-based LDs were reported in 1996 by Nakamura and co-workers [1] and commercialized from 1999 by the Nichia Corporation. Since then, huge efforts have been devoted to the optimization of the epitaxial layers (doping, defect concentration, shortening of the radiative lifetime, etc.).
