“…Measurements of the line width are heavily related to the method and instruments used in their course. Nevertheless an external cavity with a grating in Littrow mount produced a line-width of 10 kHz [74]. This line-width was later considerably narrowed to as low as 300 Hz by appropriate detuning of the external cavity feedback phase from the resonance with the field reflected from the AR-coated facet of the SOA [75].…”

External cavity tunable lasers have been around for many years and now constitute a large group of semiconductor lasers featuring very unique properties. The present review has been restricted to the systems based on the edge emitting diode lasers set-up in a hybrid configuration. The aim was to make the paper as concise as possible without sacrificing, however, most important details. We start with short description of the fundamentals essential for operation of the external cavity lasers to set the stage for explanation of their properties and some typical designs. Then, semiconductor optical amplifiers used in the external cavity lasers are highlighted more in detail as well as diffraction gratings and other types of wavelength-selective reflectors used to provide optical feedback in these lasers. This is followed by a survey of designs and properties of various external cavity lasers both with mobile bulk gratings and with fixed wavelength selective mirrors. The paper closes with description of some recent developments in the field to show prospects for further progress directed towards miniaturization and integration of the external cavity laser components used so far to set-up hybrid systems.

“…2 In particular, if an output facet of the LD is processed with an antireflection ͑AR͒ coating, the LD is strongly coupled to the external cavity. [3][4][5] Tiziani, Franze, and Haible proposed a Littman-cavity-based light source that provided a continuous wavelength tuning range of 25 nm by using an ARcoated LD. 6 A tuning range of 4 nm was obtained with an intracavity glass plate as the fine tuning device, and an AR-coated 633-nm LD in the Littrow configuration.…”

“…6 ECDLs have long been a source of great interest due to their wide wavelength tuning capability, high output power, and, of course, the narrow linewidth available with an external cavity. 7,8 To operate the ECDL such that the wavelength is tuned in a continuous, mode-hop-free manner, which is essential for successful frequency stabilization, a tuning contour plane was first recorded and is shown in Fig. 1.…”

Mode referencing of an external cavity diode laser for continuous frequency stabilization

Abstract. The output of an external cavity diode laser ͑ECDL͒ is frequency stabilized to a water ͑H 2 O͒ vapor absorption line at 935 nm using wavelength modulation spectroscopy ͑WMS͒ by means of a dualfeedback locking loop. A novel mode-referencing technique is presented that, in conjunction with the feedback locking mechanism, helps improve the overall frequency-locking system. The mode-referencing enables the device output to maintain its locked frequency in the presence of environmental and other effects, which may cause the operational characteristics of the laser to drift.
