    • 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.
    • 激光腔双光子光谱包括增益介质,第一反射器,第二反射器,电泵浦模块和双光子吸收单元。 第一反射器设置在增益介质的一侧。 第二反射器相对于第一反射器可移动地设置在增益介质的一侧。 电抽运模块电连接到增益介质。 因此,增益介质能够发射光束,该光束在第一反射器和第二反射器之间来回弹起并形成通过增益介质增强的激光束。 设置在增益介质和第二反射器之间的双光子吸收单元包括多个双光子吸收介质。 双光子吸收介质吸收在第一反射器和第二反射器之间反射的激光束的一部分,然后发射荧光。

    • An candle-like lighting device includes a light body having a diffuser, a light guider and a light source; the diffuser having a plurality of diffusing particles mounted therein; the light guider having a reflecting portion defined at one end thereof and having a refracting portion defined at another end thereof, the diffuser sleeving the light guider; and the light source assembled to the light guider. Wherein, partial light beams from the light source are reflected by the reflecting portion toward the refracting portion and are refracted by the refracting portion into the diffuser; simultaneously, rest light beams form the light source are directly transmitted toward the refracting portion and are refracted by the refracting portion into the diffuser; as a result, the refracted light beams are diffused by the diffusing particles in the diffuser.
