Multiheterodyne frequency comb spectroscopy without mode-locked lasers is reported in the near-infrared C and L telecommunication bands. The system without active stabilization combines high signal-to-noise ratio, rapid tuning and moderate multiplex spectral span.
We obtained an ultraviolet frequency comb of 1.58 W in average power by frequency quadrupling a high-power large-mode-area fiber chirped-pulse amplifier at 1032 nm, whose carrier envelop ephase was stabilized down to a linewidth of 2.42 m Hz via feedback control on the Ti:S seed oscillator.
The Avalanche Photodiodes (APDs) are widely used in a variety of optical application requiring high sensitivity, such as long-distance optical communication and optical distance measurement, because the APDs can detect the low level light. APDs accompanied with the Transimpedance Amplifier (TIA) are utilized on the receiver side in the communication system. The trend of integrating the active optical...
High power carrier-envelop phase stabilized 1030 nm pulses was generated by amplifying the fractional output spectrum of a passive mode-locked Ti:sapphire laser, exhibited 4.89 mHz long-term frequency fluctuation and 1.9 mHz beat signal linewidth.
We demonstrate a passive synchronization between a high power nanosecond fiber laser and a femtosecond Ti:sapphire laser with a cavity-length mismatch tolerance up to 8 cm and a timing jitter of 13 ps.
