Simple, low power microsystem for saturation spectroscopy |
摘要 |
<p>A spectroscopic assembly (7) is provided. The spectroscopic assembly includes a thermal isolation platform, a gas reference cell (40) encasing a gas (41) and attached to the thermal isolation platform, the gas reference cell (40) having at least one optically-transparent window (415), and at least one heater configured to raise a temperature of the encased gas (41). When a beamsplitter (30) is configured to reflect a portion of an input optical beam (20) emitted by a laser (10) to be incident on the at least one optically-transparent window (415) of the gas reference cell (40), the reflected portion of the input optical beam (20) is twice transmitted through the gas (41). When a detector (350) is configured to receive the optical beam (25) twice transmitted through the gas (41), a feedback signal (50) is provided to the laser (10) to stabilize the laser.</p> |
