“…On the other hand, it is well known that birefringence can be induced in an isotropic transparent material by external force through the photo-elastic effect. This effect has been used for various applications, such as stress analysis inside a material [10]. Moreover, SRS relies on the polarization of the input pump light [11].…”

In this letter, the dependence of stimulated Raman scattering spectra on external pressure levels of tens of kPa and the polarized pump light is investigated in optical fibers. The Raman peaks show blueshift under a lower external pressure because of the self-phase modulation. But under a higher external pressure, the Raman peaks begin to redshift, because the change of the inter-tetrahedral angle of the glassy AX 2 systems plays a more important role. Moreover, the shifts of an elliptically polarized pump beam are smaller than the those of a linearly polarized pump beam under external pressure. These results could provide new applications for silica fibers as optical frequency generators or stress sensors.

“…23) Therefore, SPE microscopy has been expected to permit the acquisition of three-dimensional (3D) images reflecting ultraviolet absorption resonances. Additionally, SPE microscopy has an advantage that it allows a single laser configuration [19][20][21][22][23] without using sophisticated pulseshaping techniques. 9) This simplifies the setup compared with other FWM microscopy techniques.…”

We demonstrate that two distinct images can be simultaneously acquired using the dual-band configuration of stimulated parametric emission (SPE) microscopy, which is based on the four-wave mixing process enhanced by two-photon electronic resonance. The dual-band SPE microscopy utilizes two SPE signals simultaneously generated at different wavelengths. In the experiment, we image stained and unstained biological tissues, and obtain two different images for each sample. Additionally, we propose an axial differential imaging technique to improve the contrast of SPE images, and verify its applicability to biological imaging. #
