Its tuning range of laser wavelength is narrower than that first-order distributed feedback dye laser, but lower noise and more stable laser operation is obtained. Single picosecond laser pulses tunable in the range of 543 nmto 596 nm can be produced by using different laser dye solutions. The tuning range of the second-order distributed feedback dye laser is extended to the shorter wavelengths which are close to pumping wavelength. | Picosecond laser pulse generation by second order distributed feedback dye laser
