技術摘要:
A laser cavity two-photon spectroscopy includes a gain medium, a first reflector, a second reflector, an electrical pumping module, and a two-photon absorption cell. The first reflector is disposed at a side of the gain medium. The second reflector is movably disposed at a side of the gain medium relative to the first reflector. The electrical pumping module is electrically connected to the gain medium. Therefore, the gain medium is able to emit a light beam, which bounces back and forth between the first reflector and the second reflector and forms a laser beam through enhanced by the gain medium. The two-photon absorption cell disposed between the gain medium and the second reflector includes a plurality of two-photon absorption mediums. The two-photon absorption mediums absorb a portion of the laser beam reflected between the first reflector and the second reflector and then emit fluorescence.

Claim 1:
1. A laser cavity two-photon spectroscopy, comprising:
a collimation tube;
a gain medium disposed in the collimation tube;
a first reflector, disposed at a side of the gain medium;
a second reflector movably disposed at a side of the gain medium relative to the first reflector;
an electrical pumping module electrically connected to the gain medium, such that the gain medium is able to emit a light beam, and the light beam bounces back and forth between the first reflector and the second reflector and forms a laser beam through enhanced by the gain medium;
a two-photon absorption cell disposed between the gain medium and the second reflector, wherein the two-photon absorption cell comprises a plurality of two-photon absorption mediums, the two-photon absorption mediums absorb a portion of the laser beam reflected between the first reflector and the second reflector and then emit fluorescence; and
a first lens disposed in the collimation tube and between the gain medium and the two-photon absorption cell for focusing the laser beam into the two-photon absorption cell.
