Dual-wavelength (DW) operation of Yb:KGW laser was demonstrated using a 1 mm-thick BRF. A series of DW pairs with wavelength separation of around 0.5 nm ($Delta nu approx 0.14$ THz) and 4 nm ($Delta nu approx 1.1$ THz) over the range of gain bandwidth were generated.

The generation of a conical refraction (CR) laser output with excellent quality directly from the oscillator based on a separate gain medium (Nd:YVO4) and an intracavity CR element (KGW) was demonstrated. The decoupling of the gain and CR media reduced the complexity of the setup and has the potential for power scaling using diode pumping.

Spinal bone metastases often present as a diffuse combination of osteolytic and osteoblastic disease. Photodynamic therapy (PDT) is a minimally invasive therapy that has been shown to locally ablate cancer cells within the bony spine. To optimize patient-specific treatment protocols and ensure safety of critical neural structures, the responsivities of the heterogenous tissues to PDT must be known. This work derives a PDT threshold value for the spinal cord using a benzoporphyrin derivative monoacid (BPD-MA) photosensitizer.

We have developed a novel monolithic dual-wavelength semiconductor InAs/InP quantum-dash (QD) C-band DFB laser. A record narrow optical linewidth below 30 kHz and relative intensity noise (RIN) of less than −150 dB/Hz are experimentally demonstrated for the two optical modes stemming simultaneously from a single cavity of a free running dual-wavelength semiconductor QD laser.

Experimentally is demonstrated the transmission of High Definition-Television signals by using two microwave photonic notch Filters. The filtering effect is generated by the use of a single mode optical source, the chromatic dispersion parameter exhibited by a standard fibers and its length.
