    • In a color photographic recording material comprising two red sensitive silverhalide emulsion layers of differing speed and two green sensitive silver halide emulsion layers of differing speed and a blue sensitive silver halide emulsion layer wherein each of the silver halide emulsion layers has associated with it a non-diffusing color coupler, and in which the more sensitive red sensitive silverhalide emulsion layer and the more sensitive green sensitive silver halide emulsion layer together form a comparatively more sensitive emulsion layer unit, the sensitivity for red and green light as well as for blue light is increased by placing the yellow filter layer immediately below the comparative more sensitive emulsion layer unit.

    • The invention relates to a method and device for determining the output power of a semiconductor laser diode being operated with a diode current. A defined measuring current, which is less than the threshold current of the semiconductor laser diode, is conducted in a conducting direction through the semiconductor laser diode. The forward voltage drop across the semiconductor laser diode is measured, and the temperature of the laser-active region of the semiconductor laser diode is determined from the measured forward voltage by using at least one calibration curve. The invention makes a simple and precise determination of the output power possible without requiring an additional measuring device, for example, a monitor diode.
    • 本发明涉及一种用于确定用二极管电流工作的半导体激光二极管的输出功率的方法和装置。 定义的测量电流小于半导体激光二极管的阈值电流,通过半导体激光二极管在导通方向上进行。 测量半导体激光二极管上的正向压降,并且通过使用至少一个校准曲线从所测量的正向电压确定半导体激光二极管的激光器有源区域的温度。 本发明能够简单且精确地确定输出功率,而不需要额外的测量装置,例如监视二极管。
