• Compact intra-cavity spectroscopic measurements may be obtained with any material that has an absorption signature under the gain bandwidth of a fiber laser. Experiments have demonstrated that compared with a regular absorption scheme, an increase in sensitivity is achieved when using the intra-cavity configuration. The practical limit for this enhancement is given by the fiber laser noise. Since intra-cavity spectroscopy is essentially a single beam technique, the application of dual-beam noise reduction techniques is not possible. However, considering that a single-mode fiber can support two modes of polarization, we have used a polarization beam splitter to create two independent cavities (x and y polarization) with the same noise, one cavity of which contains the absorber. For the first time, this permits the convenient use of Balanced Ratiomeric Detection in conjunction with an intra-cavity absorption arrangement.
