A Coin-Sized Oxygen Laser Sensor Based on Tunable Diode Laser Absorption Spectroscopy Combining a Toroidal Absorption Cell

Laser gas sensors with small volume and light weight are in high demand in the aerospace industry. To address this, a coin-sized oxygen (O<sub>2</sub>) sensor has been successfully developed based on a small toroidal absorption cell design. The absorption cell integrates a vertical-cavit...
