Dual optical frequency combs with ultra-low relative phase jitters from 550 nm to 1020 nm for precision spectroscopy

Eunmi Chae, Kota Nakashima, Kosuke Yoshioka

Here, ultra-low relative phase jitters over a wide optical spectrum were achieved for dual Ti:Sapphire optical frequency combs. The two optical frequency combs were independently p…

Direct Phase Locking of a Ti:Sapphire Optical Frequency Comb to a Remote Optical Frequency Standard

Eunmi Chae, Kota Nakashima, Takuya Ikeda +2

We report on an ultralow noise optical frequency transfer from a remotely located Sr optical lattice clock laser to a Ti:Sapphire optical frequency comb through telecom-wavelength…

Generation of highly pure Schrödinger's cat states and real-time quadrature measurements via optical filtering

Warit Asavanant, Kota Nakashima, Yu Shiozawa +2

Until now, Schrödinger's cat states are generated by subtracting single photons from the whole bandwidth of squeezed vacua. However, it was pointed out recently that the achievable…
