External cavity diode laser with broad-area laser diode is operated up to the output power of 160 mW at the injection current of 850 mA and the bandwidth of 80 pm at a wavelength of 648 nm in external cavity. High slope efficiency of output power and narrow bandwidth using broad-area laser (BAL) diode, the width of active layer in the slow axis is too broad to select a specific wavelength. In this paper, more efficient wavelength selection method is investigated by confirming the tendency of grating grooves and designing to set up the wavelength dispersion direction along the fast axis of a solitary laser diode (LD) geometrically. Thus, the tunable external cavity diode laser module by using BAL diode is designed with an overall size of 49 mm x 52 mm x 48.5 mm. From injection current in the range of 650-900 mA, ECDL showed excellent wavelength locking behavior without a non-shift of the peak wavelength. Here, the tuning range is 4 nm with maintaining the narrow bandwidth of 80 pm and up to the output power of 100 mW. A side-modesuppression of 36.5dB is also achieved at the output power of 160 mW and the injection current of 850 mA.

“…For high power and narrow bandwidth, previous research in external cavity on chip scale has been reported 16 . Ridge waveguide (RW) with tapered amplifier (TA) section for narrow bandwidth and high output power was achieved to 400 mW of output power for an emission of 629 nm and 626 nm at a TA current of 1.5 A.…”

“…Moreover, the constraints on the optical path inside the resonator eliminates the use of space-consuming fast axis and slow axis collimator pairs, as it was the case in [8] and [9]. Instead, a single standard gradient-index (GRIN) lens from the company Grintech is chosen.…”

“…However, they require bulky mechanical parts, are sensitive to misalignments, and unsuitable for use in harsh environments. Red-emitting lasers using a reflection Bragg grating (RBG) as external mirror have recently been demonstrated [8], [9]. They operate without moving parts, enabling a reduction of an order of magnitude of the device dimensions.…”

A miniaturized, standalone tunable semiconductor laser module operating at a wavelength of 633 nm with a footprint as small as 10 mm 5 mm is presented. The module is based on an external cavity diode laser system with no moving parts and features a frequency tuning range of 25 GHz with a spectral linewidth of approximately 10 MHz. An output power of 10 mW within a nearly diffraction-limited beam is demonstrated. The electrical power consumption, including thermal management, is around 0.7 W.Index Terms-Absolute distance interferometry, external cavity diode laser (ECDL), micro optical bench, tunable diode laser.

“…These gratings was applied by two types of the diffraction grating and volume Bragg grating(VBG). In the reference [3], the narrow striped(RW) laser with the TA section showed a threshold current of 700 mA, a slope efficiency of 0.48 W/A, and a maximum output power of 400 mW at a TA current of 1.5 A. Despite the reduction of the slope efficiency as compared with the RW laser alone, the limitation of output power of RW laser due to the catastrophic optical damage could be clearly overcome by a TA section.…”

An front facet-low reflection coated broad-area laser(BAL) diode with an emitter size of 50 µm x 1µm and a chip length of 2000 µm is operated in the external cavity diode laser(ECDL). For wavelength stabilization and narrow spectral width, the diffraction grating is used in a Littrow configuration. At an injection current of 1.5 A, a output power of 0.65 W with a slope efficiency of 0.85 A/W, which is comparable to those of a solitary BAL diode, could be achieved with a spectral width of 120pm which is about 77 % narrower as compared to a solitary BAL diode. The peak wavelength stability below 10 pm was obtained in the wide range of output power up to 0.65 W.
