| Research Abstract |
In this research, we have demonstrated a wide-wavelength-range waveguide dye lasers using random scattering active media. These lasers have high efficiency and high peak power output. And, we have demonstrated second harmonic generation from these lasers, and achieved wavelength range near ultraviolet from yellow, and blue from near infrared.
Moreover, we have demonstrated distributed feedback waveguide blue laser using Fluorescent Brightener 135 and spirobifluorene derivative (HBP-Spiro). These blue lasers exhibit high efficiency and long-lifetime for operation.
