Abstract

A cryostat has been designed for the refrigeration of a semiconductor diode laser (presently GaAs), using a flow of helium gas with controlled temperature. The possibility of independent adjustment of the injection current and of the temperature of the GaAs laser support allows cw emission over a wide wavelength range (∼100 Å for a given diode) while maintaining single-mode operation. A long-term frequency stability of ±30 MHz of the free-running single-mode laser has been obtained. By varying the dc injection current, it was possible to achieve linear scanning of the mode frequency, step by step or continuously, over at least 20 GHz without hopping. Possible applications in optical pumping and high-resolution spectroscopy are discussed.
