Holographic injection locking of a broad area laser diode via a photorefractive thin-film device.

چکیده
We demonstrate locking of a high power broad area laser diode to a single frequency using holographic feedback from a photorefractive polymer thin-film device for the first time. A four-wave mixing setup is used to generate feedback for the broad area diode at the wavelength of the single frequency source (Ti:Sapphire laser) while the spatial distribution adapts to the preferred profile of the broad area diode. The result is an injection-locked broad area diode emitting with a linewidth comparable to the Ti:Sapphire laser.

Injection locking suppression of coherence collapse in a diode laser with optical feedback
The effects of injection locking a laser diode which is also subject to varying levels of optical feedback from an external Ž . reflector are investigated. It is found that the locking range of a laser diode with optical feedback LDWOF is reduced relative to that of a solitary laser diode depending on both the increased photon lifetime and the amount of optical feedback. When the LDWOF is locke...
متن کاملInjection locking of Fabry-Pérot lasers and the temperature dependence of their emission in self- seeded WDM passive optical networks
The influence of temperature on coated (2%) and uncoated Fabry-Pérot laser output in a proposed colorless WDM system with self-seeding via modulation averaging reflector is studied. In particular, the connection between the information about the optical laser output from the laser integrated monitor photodetector and optical power output of the entire system with temperature change of the laser...

We explored a path of achieving high quality phase-locking of broad-area laser diode (BALD) array that operates at high electrical to optical power conversion efficiency (PCE). We found that (a) improving single transverse mode control for each individual BALD, (b) employing global Talbot optical coupling among diodes, and (c) enhancing strength of optical coupling among diodes are key factors ...
متن کاملLocking and wavelength selection of an ultra-collimated single-mode diode laser bar by a volume holographic grating.
Wavelength-locking by a volume holographic grating (VHG) is reported for a diode laser bar with 49 single mode emitters, fitted with a dual-axis collimation phase-plate for smile elimination and excellent beam pointing correction. The much-improved VHG feedback with the ultra-collimated array beam gives 100% wavelength locking at 975 nm over a 17°C temperature range and external cavity lengths ...
متن کاملOrganic and Molecular Electronics
Over recent years, a wide variety of challenges aiming for electrical pumping of organic laser diodes have been addressed. However, organic laser diodes have difficulty gaining widespread application due to their high lasing thresholds under electrical pumping. A variety of organic semiconductors have been developed to reduce the lasing threshold, which include not only small molecular material...
