摘要： The present invention relates generally to semiconductor lasers and laser projection systems. According to one embodiment of the present invention, a projected laser image is generated utilizing an output beam of the semiconductor laser (12). A gain current control signal is generated by a laser feedback loop to control the gain section (12B) of the semiconductor laser. Wavelength fluctuations of the semiconductor laser are narrowed by incorporating a wavelength recovery operation in a drive current of the semiconductor laser and by initiating the wavelength recovery operations as a function of the gain current control signal or an optical intensity error signal. Additional embodiments are disclosed and claimed.

摘要： An external cavity laser source (10) is provided comprising an external laser cavity (10), a tunable distributed Bragg reflector (20, DBR), a DBR tuning element (22), an output reflector (30), a semiconductor optical amplifier (40, SOA), a frequency-selective optical coupler/reflector (50), and a wavelength conversion device (60). The tunable DBR, the DBR tuning element, the SOA, and the output reflector are configured to generate a fundamental laser signal characterized by a fundamental bandwidth that is narrower than the QPM bandwidth of the wavelength conversion device and can be tuned to a fundamental center wavelength within the QPM bandwidth. The frequency-selective optical coupler/reflector (50) is configured for substantially non-reflective two-way transmission of optical signals at the fundamental center wavelength and is further configured for substantially complete reflection of wavelength-converted optical signals generated by the wavelength conversion device. The output reflector (30) is configured for substantially non-reflective transmission of wavelength-converted optical signals generated by the wavelength conversion device and for substantially complete reflection of optical signals at the fundamental center wavelength.

摘要： An optical package is provided comprising a laser diode and a wavelength conversion device. The laser diode and the wavelength conversion device define an external laser cavity and the wavelength conversion device is tilted relative to the output face of the laser diode to define a tilt angle Φ that is less than approximately 85°. The input face of the wavelength conversion device comprises a pair of tapered facets and a microlens. The pair of tapered facets and the microlens are defined on the input face such that they share respective portions of the facial waveguide region on the input face, with the tapered facets occupying peripheral portions of the facial waveguide region on the input face and the microlens occupying an interior portion of the facial waveguide region on the input face. Each of the pair of tapered facets define a facet angle α within the facial waveguide region that is less than the facet angle α and is greater than approximately 45°. Additional embodiments are disclosed and claimed.
