“…The slave output is split into two parts to provide light for the Zeeman slower, MOT, probe and injection monitoring. The master laser is an external cavity diode laser (ECDL) system built in the Littrow configuration [53] using an anti-reflection coated laser diode (LD) (Nichia NDBA116T), an aspheric lens (Thorlabs C230TMD-A) and a holographic grating (Thorlabs GH13-18V). A thermistor (TDK B57861S0103F045) embedded in the laser diode holder monitors the diode temperature, a piezoelectric transducer (PZT) (Thorlabs AE0203D08F) attached to the grating is used to tune the wavelength of the laser, and a Peltier cooler (ETH-127-10-13-S-RS [51]) is used to tune the diode temperature.…”

The realization of compact high-power narrow-linewidth laser sources in the visible range has been a long-standing interest for the atomic physics community, especially in the field of laser cooling and trapping of alkaline-earth and alkaline-earth-like atoms. We report a simple master-slave injection-locked laser system capable of generating 500 mW at 460.86 nm with a linewidth of 1.6 MHz to realize magneto-optical trapping of strontium atoms on the $$5s^{2} \ ^{1}\mathrm {S}_{0}-5s5p \ ^{1}\mathrm {P}_{1}$$ 5 s 2 1 S 0 - 5 s 5 p 1 P 1 transition. The master laser used is an external cavity diode laser built with an anti-reflection coated laser diode in a Littrow configuration and the slave laser is built with a recently launched single mode high power GaN laser diode. We characterized the frequency noise, injection stability, spectral purity and relative intensity noise of the laser system. The reported laser system is used routinely to produce $$10^7$$ 10 7 strontium atoms at a temperature of 10 mK in a magneto-optical trap. The laser system offers a prominent alternative to the existing frequency-doubled laser systems in terms of cost, design flexibility, electrical power consumption, ease of scaling, intensity stability, and frequency tunability. The proposed system is also an effective solution for space-based experiments where a laser system’s size, weight, and electrical power consumption are crucial design parameters.

“…Developments in related fields such as deposition, power supplies and optical design led this type of lasers to become efficient and single mode lasers. This type of lasers can be used for various applications such as laser spectroscopy experiments, the telecommunications industry, a source for pumping other lasers, measuring and manipulating the quantum state of atoms, laser cooling and generation of terahertz radiation [2][3][4][5][6][7][8][9][10][11]. Nowadays, using lasers with varying wavelengths is an interesting field of research; therefore, lasers will turn more applicable when their wavelengths can be tuned.…”

“…ECDLs will often simultaneously support two or more closely-spaced longitudinal cavity modes with the total output power split between modes such that the effective power is substantially reduced. ECDLs have replaced complex and expensive traditional dye and Titanium Sapphire lasers as the workhorse laser of atomic physics labs [8,9]. Moreover, dual wavelength Littman ECDLs are used for continuous terahertz radiation generations and also differential absorption spectroscopy [13].…”

In this paper, tunability of four near-infrared semiconductor lasers which typically lase at 783nm, 808 nm, 892 nm and 980 nm is studied. Both Littrow (wavelength dependent beam direction setup) and Littman (wavelength independent beam direction setup) configurations have been used for single mode tuning. In addition, the tunability of 783 nm laser in dual mode tuning is studied in both Littrow and Litman configurations. The wavelength and the power of the output beam of the laser have been measured. In all four cases, Littrow configuration shows a little better tuning range. In both Littrow and Littman configurations, the wavelengths near the main wavelength of the laser had more power. The highest achieved power of these lasers in the Littrow setup was more than that of the Littman setup. Moreover, the tuning speed and effect of tuning on the bandwidth of the laser were investigated.
