Line tunable visible and ultraviolet laser
A novel method of making a line tunable, visible and near ultraviolet, laser source is proposed and ::: demonstrated. It requires only a single laser and 2 nonlinear crystals. It can produce outputs with ::: wavelengths that cover much of the spectrum from 0.26 to 0.67 mm.
The mathematical representation of modulation coefficient and intrinsic phase delay of PZT fiber-optic phase modulator are given. To study the temperature character, this paper design two measure system with a Mach-Zehnder and a Sagnac interferometer and get the experimental result curve which show that both parameters are linear with temperature approximately in set temperature range.
