摘要：
We present a mode-mismatched continuous wave (cw) achromatic thermal lens experiment in which the pump beam is focused in the presence of a collimated probe beam. This scheme presents a distinct advantage over mode-matched thermal lens experimental methods in that it considerably reduces chromatic aberrations. Further, using the proposed method, we measure the near infrared spectrum of distilled water. The results are in good agreement with previous transmission measurements.
