Ultrafast Light Sources

In our group, we advance state-of-the-art ultrafast laser systems to achieve purpose-tailord and waveform-controlled laser pulses spanning the visible to mid-infrared spectral range. These efforts center on pushing the limits of commercially available laser technology to address the challenges of ultrafast science.

Laser Oscillators and Optical Parametric Amplifiers (OPAs). We focus on developing and optimizing laser oscillators and optical parametric amplifiers (OPAs) to generate few-cycle laser pulses with high peak intensities and tunable wavelengths. OPAs play a pivotal role in extending the spectral range of ultrafast pulses to mid-IR, enabling precise control over wavelength, bandwidth, and temporal properties. 

Spectral Broadening and Pulse Compression. To achieve few-cycle laser pulses, we employ spectral broadening techniques using photonic crystal fibers, gas-filled hollow-core fibers, and Herriott cells. These methods increase the bandwidth of laser pulses, laying the foundation for tailored ultrashort pulses.
