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

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,

Extreme UV (XUV) frequency comb generation in the wavelength range of 51 to 85nm is reported based on highorder harmonic generation of two consecutive IR frequency comb pulses that were amplified in an optical parametric chirped pulse amplifier. The

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

We demonstrate kHz-level “Ramsey-comb” spectroscopy using two amplified frequency comb pulses. This concept enables significantly improved accuracies on two-photon transitions as shown with rubidium and cesium, and is extendible to XUV wavelength

Summary form only given. We demonstrate the new concept of a “Ramsey comb”, which is based on Ramsey spectroscopy [1] over multiple time zones using a frequency comb laser [2]. In contrast to Ramsey's well-established technique of separated oscil

We report on a high-power quasi-CW pumped Nd:YAG laser system, producing 130 mJ, 64 ps pulses at 1064 nm wavelength with a repetition rate of 300 Hz. Pulses from a Nd:YVO(4) oscillator are first amplified by a regenerative amplifier to the millijoule
