Gain materials for visible and infrared lasers

March 10, 2022

In addition to introducing recent trends in the field of material development for solid-state lasers, this webinar will provide insights into the requirements for host materials for different types of laser applications and the challenges associated with their fabrication.

Webinar

In this webinar hosted by the Laser Systems Technical Group, Christian Kränkel will share his latest research in the development of novel gain materials. The first part of the webinar will be devoted to investigations on visible lasers based on trivalent praseodymium and terbium as the active ions. Kränkel will discuss the requirements for host crystals for visible lasers and briefly introduce crystal growth techniques before presenting the current state of the art in this field.

The second part of the webinar will be on current developments in the field of sesquioxide host materials for high power infrared and mid-infrared lasers based on trivalent ytterbium, thulium, or erbium as active ions. Recently, they have discovered significantly reduced melting points in a wide range of compositions of mixed sesquioxide crystals, which – for the first time – enables their growth by the established Czochralski-method. By compositional tuning in the ternary system Y2O3 – Sc2O3 – Lu2O3, they aim to tailor the emission spectra to support shortest pulse durations in efficient ultrafast mode-locked lasers for different wavelength regions.

In addition to introducing recent trends in the field of material development for solid-state lasers, this webinar will provide insights into the requirements for host materials for different types of laser applications and the challenges associated with their fabrication. Moreover, the audience will learn about typical trade-offs associated with the optimization of a gain material for a particular purpose.
