LAB

Ultrafast Lasers & Photonics Laboratory

Coherent light sources emitting ultrashort pulse and high peak power are essential for investigation on diverse nonlinear and ultrafast phenomena. We are developing ultrafast solid-state lasers operating in various spectral ranges using Ti:sapphire, Yb:KYW, Yb:KLuW, Cr:forsterite, Cr:YAG, Cr:ZnS, etc. Recently, waveguide lasers which simplify a solid-state laser cavity into on-chip scale are in great interests. In particular, waveguide lasers can generate high-repetition-rate (GHz-level) mode-locked pulses to be utilized in fast sampling and high precision metrology. In addition, novel types of saturable absorbers necessary to achieve stable and self-starting pulse formation are developed based on low-dimensional carbon nanostructures.
