Inhalt der Summer School

summerschool inhalt 1The course reviews the basic concepts of advanced highly efficient rare earth ion doped solid-state lasers based on 4f-4f transitions of laser ions such as Yb3+, Tm3+, Er3+, Pr3+, and Tb3+ which have opened new prospects for laser applications at various wavelengths and power regimes. The main emphasis is placed on the interplay between materials aspects and most relevant spectroscopic as well as laser related properties in the search for new solid-state laser systems.

For the near infrared spectral region Yb3+-doped laser crystals feature very high efficiencies and reduced heat generation due to small Stokes-losses between pump and laser photons. In particular, Yb3+:Lu2O3 possesses high thermal conductivity and has been operated at record slope efficiencies of 80% in continuous wave operation and at more than 100 W of average power in the mode-locked sub-ps operation regime. Laser diode pumped, highly efficient 2-µm Tm3+- and 3-µm Er3+-lasers with special interest for medical applications are based on interionic interactions of Tm3+ and Er3+ laser ions, respectively.

 

Breakthroughs regarding efficient visible coherent light generation have been achieved with Pr3+- and Tb3+-lasers operating in the green, orange, and red spectral region under blue semiconductor laser pumping. Here both, the development of blue semiconductor pump lasers and the use of suitable short wavelength hosts with minimized excited state absorption of the laser ions contributed to major achievements.

 

Based on 4f-5d transitions, the ion Ce3+ exhibits broad, tunable transitions in the ultraviolet spectral region. In contrast to the well shielded inner 4f- levels of rare earth ions, the outer 5d-orpitals are not shielded resulting in a strong electron-phonon coupling of 5d-electrons - a situation which is similar to transition metal ion doped laser crystals like Ti-Sapphire.

 

summerschool inhalt 2The course will cover the following areas in detail:

  • Basic laser aspects
  • Growth and properties of laser crystals
  • Spectroscopic properties of rare earth ion doped laser materials
  • Laser parameters and related properties of rare earth ions
  • Visible and near infrared rare earth ion solid-state lasers
  • Broadly tunable lasers

Guenter Huber, born 1947 in Ludwigsburg/Germany, received his Ph.D. degree in physics from the University of Stuttgart/Germany in 1975. He was research staff member of the Max-Planck-Institute/Stuttgart/Germany and of the Institute of Applied Physics of Hamburg University. He became Professor of Physics at Hamburg University in 1982. In 1986/1987 he was guest Professor at Ginzton Lab., Stanford University, USA. At Hamburg University he served as Director of the newly established Institute of Laser Physics (1991), Vice Dean (2000), Dean of the Faculty of Physics (2003-2006), and board member of the University Council (2008-2016).

His research activities in experimental laser physics are focused on diode pumped solid-state lasers, the development and fundamental characterization of new laser materials based on transition metal and rare earth ions. He has published more than 300 original papers in his research field.

He is Fellow of OSA, EPS and received the Quantum Electronics-Optics Prize of EPS in 2003 and the Charles Hard Townes Award of OSA in 2013. Since 2016 he is Foreign Member of the Russian Academy of Sciences.
