We present an 880 nm quasi-continuously pumped, grazing-incidence "bounce" amplifier system, capable of producing picosecond pulses (12 - 100 ps) and tailored pulse sequences at the mJ-level. More than 1.8 mJ of pulse energy was achieved for a 58 ps

We characterize the saturable absorption of the second (E22) electronic transition of a sample of single-walled carbon nanotubes and use it to mode-lock an ytterbium fiber ring laser. The modulation depth of ~ 15% was found to be similar to the corre

Frequency comb generation and excitation of argon, neon, and helium is shown from 51 to 85 nm with amplified and harmonically upconverted comb laser pulses, resulting in an 8fold improved helium ground state ionization energy.

The capability of frequency-comb (FC) lasers to precisely measure optical frequencies is extended to the multiple-PHz domain. This frequency region, which covers the extreme ultraviolet (XUV, wavelengths shorter than 100 nm), was previously not acces

We report on an 880 nm quasi-continuously pumped Nd:YVO4 grazing-incidence “bounce” amplifier, operating at a 300 Hz repetition rate. More than 70 dB small signal gain is achieved with a single crystal. Combined with fast programmable modulators,

We recently demonstrated that the spectroscopic accuracy and resolution of optical frequency combs can be obtained from a series of Ramsey-like measurements using only two amplified frequency comb pulses at variable delays. In this work we present a
