Conductivity and discharge guiding properties of mid-IR laser filaments
The electric properties of mid-IR filaments in air have been investigated in comparison with their more traditional near-IR counterparts. Although the number of ions left after the pulse is similar for both sp...

10-mJ optically synchronized CEP-stable chirped parametric amplifier at 1.5 μm
We demonstrate the generation of 10-mJ 1.5-μm few-cycle pulses from a 4-stage OPCPA system. The system is based on a fusion of femtosecond DPSS Yb technology and a picosecond Nd:YAG pump laser. In a first prel...

Spectroscopy and lasing of cryogenically cooled Yb, Na:CaF2
Absorption, photoluminescence and cw-lasing properties of a novel Na+-codoped Yb3+:CaF2 laser crystal are investigated in the temperature range from 10 K to 290 K. Cryogenic cooling leads to the disappearance of ...

Multimillijoule Optically Synchronized and Carrier-Envelope-Phase-Stable Chirped Parametric Amplification at 1.5 μm
Efficient infrared 35-THz-wide parametric amplification at 1.5 μm with the energy of ~10 mJ is obtained in a 4-stage OPCPA using a combination of a 1030-nm 200-fs Yb- and a 1064-nm 60-ps Nd amplifier seeded wi...
