Passive intra-cavity phase locking of laser channels
نویسندگان
چکیده
A new approach for stable intra-cavity phase locking of several laser channels is presented. In this approach, special interferometric couplers are incorporated inside a laser resonator to obtain efficient self phase-locking between separate laser channels. We analyze the approach and demonstrate experimentally phase-locking of two and of four laser channels, that are derived from Nd:YAG lasers, with 92% and 83% power efficiencies respectively. 2006 Elsevier B.V.

Dynamics of two semiconductor lasers coupled by a passive resonator.
The stability of two semiconductor lasers that are spatially separated by a passive resonator is analyzed using the composite-cavity mode approach. We study the nonlinear interactions of three composite-cavity modes and identify regions of in-phase and out-of-phase laser locking in the parameter plane of the transmission coefficients of the coupling mirrors and the laser length difference. Bifu...
متن کاملMode-locking and Q-switching in multi-wavelength fiber ring laser using low frequency phase modulation.
We describe experimental investigation of pulsed output from a multi-wavelength fiber ring laser incorporating low frequency phase modulation with large modulation amplitude. The Erbium-doped fiber (EDF) ring laser generated more than 8 wavelength channels with the help of a phase modulator operating at 26.2 kHz and a periodic intra-cavity filter. For most cases, the laser output is pulsed in t...
متن کاملMethods of passive and active mode locking using intracavity optical frequency mixing.
The mode-locking technique based on intracavity second-harmonic generation is extended to sum- and difference-frequency generation. Simultaneous passive mode locking of two different types of laser in a combined cavity is thus possible. By using the same principle, a laser may be actively mode locked by injection of a pulse train from another mode-locked laser.

By spectrally slicing a single longitudinal-mode from a master weak-resonant-cavity Fabry-Perot laser diode with transient wavelength scanning and tracking functions, the broadened self-injection-locking of a slave weak-resonant-cavity Fabry-Perot laser diode is demonstrated to achieve bi-directional transmission in a 200-GHz array-waveguide-grating channelized dense-wavelength-division-multipl...
متن کاملStability Analysis of the Mode-Locking Dynamics in a Laser Cavity with a Passive Polarizer
A low-dimensional model is constructed via a variational formulation which characterizes the mode-locking dynamics in a laser cavity with a passive polarizer. The theoretical model accounts explicitly for the effects of the passive polarizer with a Jones matrix. In combination with the nonlinear interaction of the orthogonally polarized electromagnetic fields, the evolution of the mode-locked s...
