The room temperature laser generation in the yellow - green () spectral range has been demonstrated under optical pumping by a pulsed nitrogen laser of quantum dot heterostructures. The maximum achieved laser wavelength was as high as at a laser cavity length of . High values of both the output pulsed power (up to ) and the external differential quantum efficiency () were obtained at a cavity length of . Both a high quality of the laser heterostructure and a low lasing threshold () make it possible to use a pulsed InGaN laser diode as a pump source. A laser microchip converter based on this heterostructure has demonstrated a maximum output pulse power of at . The microchip converter was placed in a standard TO-18 ( in diameter) laser diode package.
