Tekhnoscan has released the Tisarius-D, a powerful source of UV to blue-green single-frequency radiation. The system is based on a Ti:Sapphire laser (700-1,050nm) and an efficient frequency doubler (350–525nm). When pumped by a standard 5–12W DPSS/fibre laser, the device delivers 100-800mW of single-frequency output, with a radiation line width of less than 10kHz at selected wavelengths within the 350–525nm range.
Electronic control systems of the laser and the resonant enhancement frequency doubler provide an auto re-lock function, allowing Tisarius-D to operate reliably and stably under variable conditions.
Tekhnoscan states that pottential high impact application areas of this system lie within atomic or molecular cooling and trapping, in situ process control of physical vapour deposition, nanostructure fabrication, atomic lithography, gas analysis, new high-precision spectroscopy experiments, trace substance detection, high speed wafer inspection, etc.
In applications related to laser cooling, the Tisarius-D is able to efficiently cools such atoms as Ca (using wavelengths of 397, 423 or 442.7nm), Mg (383nm), Pb (368.3nm), Rb (421nm), Sr (422nm), Yb (369.5nm), Er (401nm), Tm (410–420nm) and many others. In areas connected to physical vapour deposition system Tisarius-D provides precision control in deposition of such materials as aluminium (394nm), titanium (391nm), yttrium (408nm), tungsten (385nm), gallium (403nm) and others.
