Abstract
A high optical signal-to-noise ratio (OSNR), high output power, low wavelength drift, and narrow-linewidth single-longitudinal-mode (SLM) erbium-doped fiber laser (EDFL), the subject of this research, consists of three parts: main cavity, self-injection locked feedback mechanism and erbium-doped fiber amplifier (EDFA). During an observation time of 60 min, the proposed EDFL can generate SLM lasing with an OSNR > 75.04 dB. The maximum wavelength drift in that time remained at a low level of 0.0085 nm. Moreover, the maximum SLM output optical power could reach 157.20 mW. Measures of the output laser performance, such as dependence of output power variations on pump power, power spectral density of frequency fluctuation, and frequency shift of the relaxation oscillation peak, were investigated and analyzed in this research.
期刊介绍:
The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region.
Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine.
Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
