The alkali-metal vapor cell is the key sensitive element of quantum sensors such as atomic magnetometers, atomic gyroscopes, and atomic clocks. The alkali-metal vapor in the cell interacts with laser and magnetic field to achieve high-precision measurement of some physical quantities. A teaching experiment platform for parameter testing of alkali-metal vapor cells with high temperature and high pressure is constructed. According to the measured laser absorption spectrum, the pressure of the buffer gas and the density of alkali-metal atoms inside the vapor cell can be obtained. This experimental platform help students to directly observe the interaction between laser and atoms, which helps them to understand the alkali-metal vapor cell, cultivate their experimental hands-on ability and provides support for graduate and undergraduate related courses.
