چکیده
We introduce a CW two-color Ti : sapphire laser for terahertz spectroscopic applications. The laser provides two parallel beams at independently tunable wavelengths allowing one to select a difference frequency in the range from below 20 GHz to 50 THz. The laser is pumped by a single 6-W pump beam in order to keep the setup as simple as possible. Under these conditions, output powers of 150 mW per beam in the gain-maximum region are achieved.

متن کاملSingle-longitudinal-mode, tunable dual-wavelength,CW Nd:YVO(4) laser.
We report a single-longitudinal-mode CW diode-pumped Nd:YVO(4) laser emitting at both 1064 and 1342 nm with 10% optical efficiency at 20-W pump power. The measured spectral widths at 1064 and 1342 nm were less than 450 MHz and 400 MHz, respectively. The two emission wavelengths can be independently tuned over the lasing bandwidths of the dual-wavelength laser.

We report a collinear output and tunable dual-wavelength CW Ti:sapphire laser with a simple cavity configuration. The wavelength splitting range is easily tuned from 10 nm to 110 nm, which provides 56 THz bandwidth for terahertz generation. The total output power of two colors with the spatial mode of TEM(00) is between 700 mW and 300 mW, for small and large wavelength splittings, respectively,...
متن کاملSelf-Q-Switch and CW Operation of a Tunable Dual-Wavelength Er/Yb Double-Clad Fiber Laser
In this paper, a double-clad Er/Yb fiber laser with self-Q-switched and continuous wave operation depending on the pump power range is experimentally demonstrated. The linear cavity is formed on one side by a pair of cascaded tunable fiber Bragg gratings used for the selection and tuning of the generated laser lines. On the opposite side, a fiber optical loop mirror with high birefringence fibe...

For the first time we demonstrate a multiwavelength, ultrabroadband, continuous-wave, tunable, polycrystalline Cr2+:ZnSe spatially-dispersive laser, operating in the near IR spectral region. We show a dual-wavelength operation of the laser, tunable over a 600 nm spectral range (2200-2800 nm), an ultrabroadband operation of the laser, producing a continuous 135 nm wide spectrum centered at 2500 ...
