Yb:pMDT Toward the compact ultrafast laser
Ytterbium doped passive MDT have a great potential
for compact diode pumped high average power ultra-
fast laser source. Among the key characteristics are:
- Short absorption length favourable for low
brightness diode pump.
Relatively higher (than Yb:YAG) emission cross
section prevents the mode-locked pulse train
from Q-switching instabilities.
- Broad gain bandwidth for polarisation along n . p
- Two pump ranges high absorption near 980 nm and plateau-region at 940 nm.
- High cubic non-linearity leading to stable self-starting Kerr-lens mode locking.
-
All these, but also the higher anisotropy and possible further optimisation, as well as
new designs based on planar waveguides say that Yb:pMDT are real candidate for
high efficient (10% electric to optical efficiency) ultrafast source.
We offer Yb slabs with:
- Two geometry Brewster/Brewster and rectangular slab;
- Three doping levels 5, 2.5 and 1.25 at.%;
- Two hosts KYW and KGdW;
- Two orientation for the polarisation of the emission along n and n ; m p
- Various slab lengths 3, 4, 5 and 7 mm.
The thickness of 1 mm is
manufactured preserving high polishing finish.
