Abstract

New Yb:LYSB bifunctional crystal for efficient near-infrared laser emission and self-frequency doubling conversion

Highlights

  • Nowadays, solid-state lasers with emission in the visible (VIS) spectral range are used in a large variety of applications, from manufacturing and materials processing technologies to medicine, optical communication or military applications

  • We report on the development of Yb:LYSB as new bifunctional laser and nonlinear optical (NLO) crystal

  • Based on our experience on growing undoped LaxYySc4-x-y(BO3)4 - LYSB - type crystals [1], a special heating assembly that allows an effective control of both B2O3 evaporation and thermal gradients over the crucible and in the melt, was used for the growth of the incongruent melting Yb:LYSB crystal by the Czochralski method (Fig. 1)

Summary

Introduction

Solid-state lasers with emission in the visible (VIS) spectral range are used in a large variety of applications, from manufacturing and materials processing technologies to medicine, optical communication or military applications. We report on the development of Yb:LYSB as new bifunctional laser and NLO crystal. Based on our experience on growing undoped LaxYySc4-x-y(BO3)4 - LYSB - type crystals [1], a special heating assembly that allows an effective control of both B2O3 evaporation and thermal gradients over the crucible and in the melt, was used for the growth of the incongruent melting Yb:LYSB crystal by the Czochralski method (Fig. 1).
