Hybrid Mode Locked Fiber Ring Laser
Mode locked pulse generation has been reported using both active and passive mode locking schemes. Active mode locking technique has been proven to be an effective way to generate high-repetition-rate pulses by incorporating a modulator inside the laser cavity. Compared to actively mode locked lasers, passively mode locked lasers can generate pulse train at ultrashort pulse width but with relat...
متن کاملModeling of Mode-Locked Lasers
Growing demand of communication networks requires ultra-short pulses. Ultra-short pulses can guarantee high data transfer and power. Fiber lasers, which are actively or passively mode-locked to generate ultrashort pulses, are termed as Mode locked fiber lasers. There are a number of methods available for mode-locking of lasers. We have discussed most of them in this paper. At the end a model of...
متن کاملPassively synchronized Q-switched and simultaneous mode- locked dual-band Tm:ZBLAN fiber laser at 1.48- and 1.85- μm using common graphene saturable absorber
We demonstrate a dual-band Tm:ZBLAN fiber ring laser with synchronized Q-switched pulses and a dual-band simultaneous mode-locked Tm:ZBLAN fiber linear laser at 1.48 μm and 1.85 μm using a common graphene saturable absorber.

متن کاملEnvironmentally stable, simple passively mode-locked fiber ring laser using a four-port circulator.
We present here a self-starting passively mode-locked fiber ring laser with a novel cavity configuration using a four-port optical circulator. Our special ring cavity design enables highly stable mode-locked operation between 25 and 60 degrees C to be maintained without the need for any polarization-adjusting devices. The pulse width and the integrated timing jitter from 10 Hz to 10 MHz of our ...
متن کاملWavelength-tunable, passively mode-locked fiber laser based on graphene and chirped fiber Bragg grating.
We demonstrate a wavelength-tunable, passively mode-locked erbium-doped fiber laser based on graphene and chirped fiber Bragg grating. The saturable absorber used to enable passive mode-locking in the fiber laser is a section of microfiber covered by graphene film, which allows light-graphene interaction via the evanescent field of the microfiber. The wavelength of the laser can be continuously...
متن کاملImpact of pulse dynamics on timing jitter in mode-locked fiber lasers.
We investigate the high-frequency timing jitter spectral density of mode-locked fiber lasers in different mode-locked regimes. Quantum-noise-limited timing jitter spectra of mode-locked-regime-switchable Yb fiber lasers are measured up to the Nyquist frequency with sub-100-as resolution. The integrated rms timing jitter of soliton, stretched-pulse, and self-similar Yb fiber lasers is measured t...
