METHODS FOR DETERMINING OPTICAL POWER, FOR POWER-NORMALIZING LASER MEASUREMENTS, AND FOR STABILIZING POWER OF LASERS VIA COMPLIANCE VOLTAGE SENSING |
摘要 |
A method is disclosed for power normalization of spectroscopic signatures obtained from laser based chemical sensors that employs the compliance voltage across a quantum cascade laser device within an external cavity laser. The method obviates the need for a dedicated optical detector used specifically for power normalization purposes. A method is also disclosed that employs the compliance voltage developed across the laser device within an external cavity semiconductor laser to power-stabilize the laser mode of the semiconductor laser by adjusting drive current to the laser such that the output optical power from the external cavity semiconductor laser remains constant. |
