A theory of optical-microwave double resonance is developed for the case of optical detection. Lineshapes and peak values of the double resonance signal are calculated with a density matrix in the Doppler-limit approximation. The first-order dynamic Stark splitting caused by an intense optical radiation does not appear in the Doppler-limit approximation. At strong optical saturation, however, the higher-order effect causes lineshape anomaly. There is an exceptional case in which the anomalous lineshape can be observed even at rather weak optical saturation. This occurs when the lowest-order term of the signal is canceled out accidentally by a part of the higher-order terms. The anomalous lineshape observed in the infrared-microwave double resonance experiment of H_2CO is explained satisfactorily by this effect. The peak value of the signal at strong microwave saturation is calculated and compared with tire result from the rate equations.
