PErL Erbium Faserlaser

Femtosekunden Faserlaser PErL

PErL Faserlaser

Der Erbium-dotierte Femtosekunden-Faserlaser PErL ist in zwei Varianten verfügbar und eignet sich mit seiner kleinen und robusten Bauweise besonders für OEM-Anwendungen. Der Laser kann sowohl als Einzelsystem arbeiten als auch in ein komplexes System eingebunden werden. Zum Betrieb des Lasers wird einzig ein 5 Volt-Netzteil benötigt.

The very small PErL is an ultrafast laser operating in C-band (1530-1565nm). Because of its rigid design, this laser is insensitive to physical disturbances and vibration. The high stability and the repeatability of initial specifications fit the high demands in OEM applications. There exist two versions of the laser: the PErL-OEM being a cost-effective, minimalistic version without linearly polarized output, and the PErL-PM with linearly polarized output and ultra-short pulse capability.

The PErL-OEM can be ordered in the range of 250fs to up to 5ps with pulse shape close to transform-limited. The PErL laser with average power of up to 50mW is a budget-friendly solution for low-power ultrafast applications. For operating the OEM version, you only need a power source with 5V (the power adapter for standard 110/220V is supplied with the laser).

The PErL-PM features PM fiber architecture and PM fiber socket output with fiber pigtail lengths up to 1m. An optional free-space collimator is supplied on request. The system offers pulse durations as low as 50fs and is a versatile tool for semiconductor studies and for THz generation.

The high frequency electrical outputs of either version can be used as a trigger source for synchronization systems. The laser can operate either as a stand-alone pulse source or as part of complex systems.
