We present the advances in x-ray femtosecond pulse generation and the most recent
discoveries in the field of ultrashort (femtosecond) x-ray science. Nowadays x-rays show …

We compensated for chirp of optical pulses with an over-one-octave bandwidth (495–1090
nm; center wavelength of 655.4 nm) produced by self-phase modulation in a single argon …

We present a new method for measuring the spectral phase of ultrashort pulses that utilizes
spectral shearing interferometry with zero delay. Unlike conventional spectral phase …

Over the past few decades, the rapid development of ultrafast lasers, such as femtosecond
lasers and picosecond lasers, has opened up new avenues for material processing due to …

Encoding information in the time–frequency domain demonstrates its potential for quantum
information processing. It offers a novel scheme for communications with large alphabets …

The thermal properties of thin films and material interfaces play an important role in many
technologies such as microelectronics and solid-state energy conversion. This thesis …

We provide a detailed discussion of our recently developed pulse characterization
technique for few-cycle pulses, called two-dimensional spectral shearing interferometry …

Spectral phase interferometry for direct electric-field reconstruction has become a standard
technique for the measurement and characterization of extremely short laser pulses. Here …

The synthesis of nearly arbitrary supercontinuum pulse forms is demonstrated with sub-
pulse structures that maintain a temporal resolution in the few-cycle regime. Spectral …

A self-referencing technique for measuring amplitude and phase of ultrashort laser pulses is
presented. In contrast to the other methods the relative-phase ambiguities do not appear in …
