MARBURG, Germany, March 3, 2008 -- Sacher Lasertechnik GmbH said it offers a cavity frequency doubler (second-harmonic generation) for its established series of tunable diode-laser systems, such as Jaguar.
The frequency doubler allows for experimental accessing of spectroscopically important wavelengths in the visible and ultraviolet (UV) spectral regions which can otherwise not be accessed with diode lasers, Sacher said. The cavity frequency doubler consists of a ring cavity in which a periodically poled doubling crystal is positioned. The ring cavity is being stabilized on the diode lasers via a Hänsch Coulliaud locking mechanism.
The frequency doubler can be operated with tunable laser systems offering pump powers of less than 100 mW.
Depending on the power of the tunable diode-laser system, which pumps the frequency doubler optically, output powers of more than 500 mW in the visible and UV spectral region can be achieved, the company said. Features of the frequency doublers include a line width of less than 1 MHz, a tuning range of greater than 10 nm, and mode-hopping-free operation at greater than 30 GHz.
The frequency doubling now enables for spectroscopic investigation in the spectral region of 330 to 540 nm. According to Sacher, the cavity-doubled diode laser system is especially suited for optical cooling and optical traps and can also be used for interferometry, lithography and bioimaging.
