Abstract
A short external cavity (EC) providing a single frequency lasing of quantum-well diode lasers with broad optical gain profiles has been developed. A feature of the proposed EC is the use of a resonant reflector formed by two thin (with thickness of approximately 100 µm) cover glasses as a return mirror. The HL8338MG laser equipped with a similar short EC made it possible to demonstrate the continuous optical frequency tuning within 100 GHz and discrete wavelength tuning in the 12.3 nm range with an output power of approximately 20 mW. The applicability of such a tunable diode laser source for gas spectroscopy was confirmed by the observation of three krypton absorption lines near 829 nm in a low-pressure radio frequency discharge.
期刊介绍:
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
