    • Disclosed is an operational-temperature-stabilized wavelength-stabilized laser diode having an integrated temperature control unit. Such diode arrangement has combinations of the following features: at least one laser chip; heating provided by at least one PTC resistor such that a device operational temperature is controlled by this PTC resistor; a detector for determining the radiation emerging from the rear of the laser chip; an NTC resistor or a thermo-element for measuring the chip temperature. The laser chip serves a dual function of acting as a laser source and as a radiation detector, thereby eliminating any need for a separately provided radiation detector and resulting in a compact device. All the components required for temperature control, respectively, temperature stabilization, are miniaturized and integrated with the laser chip within a housing. The extremely small size of the invented laser diode opens a wide range of possible applications.
