| 英文摘要 | A laser diode package incorporating a first laser diode (or diode laser array) for providing a modulated light output and a second laser diode (or diode laser array) with substantially similar thermal operating characteristics which is modulated with a complementary current signal relative to the modulated current signal driving the first laser diode. The two laser diodes are mounted in close proximity to one another on a temperature controlled heat sink. For diode laser arrays, slots are provided in the heat sink between adjacent array elements. The complementary modulation of corresponding elements in each laser diode ensures that the combined heat generation by each such corresponding pair of elements is constant in time. In the case of digital modulation, the driver logic and current drivers providing the complementary modulation signals may be a modulation controlled switch routing a constant current to one or the other of each corresponding pair of laser elements. |
