本文报道了在氢气中观察到连续波非共振拉曼激光器的连续波相干反斯托克斯辐射。反斯托克斯辐射与具有高斯空间分布的泵浦和斯托克斯光束共线。当激光腔被调谐到拉曼共振中心时，外部反斯托克斯与斯托克斯功率比为百万分之26.3，并且对于从线中心的轻微失谐而言更高。提出了一种稳态理论，该理论准确地描述了反斯托克斯行为与输出斯托克斯功率和与拉曼共振的失调的函数关系。
We report the observation of cw coherent anti-Stokes emission from a nonresonant cw Raman laser in H2. The anti-Stokes emission is collinear with the pump and Stokes beams with a Gaussian spatial profile. The external anti-Stokes to Stokes power ratio is 26.3 parts per million when the laser cavity is tuned to the center of the Raman resonance and higher for slight detuning from line center. A steady-state theory is presented that accurately describes the anti-Stokes behavior as a function of output Stokes power and detuning from the Raman resonance.
