Generating arbitrary polarization states by manipulating the thicknesses of a pair of uniaxial birefringent plates
Akihiro Tomura, Makoto Nomura, Chiaki Ohae +1
We report an optical method of generating arbitrary polarization states by manipulating the thicknesses of a pair of uniaxial birefringent plates, the optical axes of which are set…
10 W injection-locked single-frequency continuous-wave titanium:sapphire laser
Tetsushi Takano, Hisashi Ogawa, Chiaki Ohae +1
High-power tunable lasers with good longitudinal and transverse modes are fundamental tools for exploring quantum physics. Here we report a high-power continuous-wave injection-loc…
Tailored Raman-resonant four-wave-mixing process
C. Ohae, J. Zheng, K. Ito +3
Nonlinear optical processes are strongly dominated by phase relationships among electromagnetic fields that are relevant to its optical process. In this paper, we theoretically and…
Dual-frequency injection-locked continuous-wave near-infrared laser
Trivikramarao Gavara, Takeru Ohashi, Yusuke Sasaki +7
We report a dual-frequency injection-locked continuous-wave near-infrared laser. The entire system consists of a Ti:sapphire ring laser as a power oscillator, two independent diode…
Generation of five phase-locked harmonics by implementing a divide-by-three optical frequency divider
Nurul Sheeda Suhaimi, Chiaki Ohae, Trivikramarao Gavara +3
We report the generation of five phase-locked harmonics, f_1: 2403 nm, f_2: 1201 nm, f_3: 801 nm, f_4: 600 nm, and f_5: 480 nm with an exact frequency ratio of 1 : 2 : 3 : 4 : 5 by…
The simplest rout to generating a train of attosecond pulses
Kazumichi Yoshii, John Kiran Anthony, Masayuki Katsuragawa
We report on new routes to generating a train of attosecond pulses. The methods are extremely simple and robust; we need to place only a few thin dispersive materials in the optica…
10 THz Ultrafast Function Generator - generation of rectangular and triangular pulse trains-
Kanaka Raju Pandiri, Masayuki Katsuragawa
We report the synthesis of arbitrary optical waveforms by manipulating the spectral phases of Raman sidebands with a wide frequency spacing line-by-line. Trains of rectangular and…
Line-by-line control of 10-THz-frequency-spacing Raman sidebands
Kanaka Raju Pandiri, Takayuki Suzuki, Akira Suda +2
We report line-by-line control of a coherent discrete spectrum (Raman sidebands) with a frequency spacing of 10.6 THz that is produced by an adiabatic Raman process. We show that t…
A Raman-type optical frequency comb adiabatically generated in an enhancement cavity
M. Katsuragawa, R. Tanaka, H. Yokota +1
We demonstrate efficient generation of a Raman-type optical frequency comb by employing adiabatic Raman excitation in an enhancement cavity. A broad frequency comb spanning over 13…
