“…The SOA chip was attached to a thermoelectric cooler to allow for control of its temperature with the accuracy of ±0.1 K. It was oriented in such a way that the active layer plane (quantum well plane) was parallel to the grating grooves since it was already found that this is an obligatory condition for ECL operation with the broad contact SOAs due to single mode operation of the SOA in direction per− pendicular to the quantum well plane [12]. The SOA chip was pulse driven (I D = 0.4 A) with the current pulses t 2−μs long and 10−kHz repetition frequency.…”

Optical properties of an external cavity laser with a semiconductor optical amplifier and two diffraction gratings are described. The laser has been pigtailed and its emission showed two peaks in the output spectrum. The wavelength of the peaks, and in particular the spectral spacing between them, could be controlled by adjusting the reflecting elements in the system. The proposed double-frequency laser may be adopted as a signal source in terahertz generators.

“…Profile of the grating grooves depends on the particular method used for their fabrication. The E-beam writing process combined with reactive ion eching (RIE) delivers gratings with rectangular grooves which have been found quite satisfactory for ECTL operation [49]. In addition, this method is particularly compatible with other processing operations involved in the MOEM technology since it enables pattern generation without any primary mask.…”

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.

“…In 1990s ECDL systems were the essential tool for atomic physics and spectroscopy because of their wavelength tuning characteristics and narrower linewidth output. Several groups have investigated the ECDL systems to improve its critical weaknesses and they published so many reviews and articles including; simplicity of construction and compactness [9], coupling efficiency [10] and optical feedback [11], frequency selection with band-pass filters [12], transmission gratings [13], Volume Phase Holographic Grating (VPHG) [14], spectral characteristic [15] and line-width measurement [16], laser wavelength control [17] and increasing the mod-hop free running range [18].…”

Tunable lasers one of the important tool of atomic manipulation and quantum interference and modern spectroscopy. However classical tunable coherence light sources such as dye lasers or optical parametric oscillators are expensive and difficult to maintain and operate. Diode lasers may be good alternative to those well-known tunable lasers with some modification such as constructing external cavity and with a good thermal stabilisation. Also many available commercial diode lasers may not cover the atomic absorption lines. To overcome those problems, we design and constructed a platform for ultra-cold tuneable external cavity diode laser system working at -50 0 C and under rough vacuum (at 28mBar). Temperature tuning capability of the system was examined utilizing a 658nm (AlGaInP) single mode laser diode. With the system designed the temperature dependent tuning range was expended to almost two fold (down to 650nm at -50 0 C) while halving the bandwidth (less than 7MHz) regarding to its room temperature (at 25 0 C) performances. As opposed to water cooling and very thick isolation that makes the laser system impractical, in our design heat dissipation was achieved by air cooling taking advantages of ease of operation, less complicated system, compactness with safety for the optical and electronic devices used. A theoretical procedure is also presented to calculate thermal control parameters including heat transfer rate, thermal isolation and heat dissipation of the system.
