    • A target gas sensing system includes a single source at a first location for generating two light beams having first and second frequencies wherein the difference between the first and second frequencies is the Raman frequency of the target gas. A difference frequency generator outputs the two light beams having the first frequency, the second frequency, and a third light beam having a third frequency that is the difference between the first and second frequencies. The first, second, and third light beams are directed toward the target gas. An input optic directs light from the third light beam, after interacting with the target gas, to a receiver for absorption spectroscopy processing, directs a fourth light beam from the target gas to a receiver for coherent anti-Stokes Raman processing, wherein the fourth light beam has a frequency of twice the first frequency minus the second frequency.
    • 目标气体感测系统包括在第一位置处的单个源,用于产生具有第一和第二频率的两个光束,其中第一和第二频率之间的差是目标气体的拉曼频率。 差分频率发生器输出具有第一频率,第二频率的第二光束和具有作为第一和第二频率之间的差的第三频率的第三光束。 第一,第二和第三光束被引向目标气体。 输入光学器件将来自第三光束的光引导到与目标气体相互作用的接收器,用于吸收光谱处理,将来自目标气体的第四光束引导到用于相干反斯托克斯拉曼处理的接收器,其中第四光 光束具有第一频率的两倍的频率减去第二频率。

    • The present invention is directed to a novel method of preparing a polymerizate, which includes the step of polymerizing a two-component composition, which includes: a first component containing at least one polycyanate reactant having at least two functional groups selected from isocyanate, isothiocyanate and combinations thereof, the polycyanate reactant being the reaction product of: a polythiol monomer having at least two thiol groups; and a polycyanate monomer having at least two functional groups selected from isocyanate, isothiocyanate and combinations thereof; and a second component containing at least one polyamine reactant having at least two functional groups selected from primary amine, secondary amine and combinations thereof. The molar equivalent ratio of (NCO+NCS) groups from the first component to (—NH2+—NH—) groups from the second component is from 0.5 to 100. The present invention is also directed to polymerizates prepared according to the method of the present invention. The present invention is further directed to photochromic articles that may be prepared from the polymerizates of the present invention.
