lasag offers laser that mixes wavelengths
The SLS 200 GX from Lasag is available for trials through rofin-baasel uK. The SLS 200 GX uses a patented process that mixes in a secondary wavelength at 532nm, but it only represents up to 15 per cent of the total energy. This mixing improves the absorption of laser energy delivering consistent results even where there are differences in the surface condition of the material. This process is aimed at getting round the
issue with copper, where as little as five per cent of laser light at 1μm is absorbed. Welds from the SLS 200 GX, Lasag
claims, are more consistent in diameter and penetration and very small spot welds down to 25μm diameter are also possible. Following the initial pulse of green light, the energy is reduced, however the main infrared energy is maintained to allow the weld pool to grow.

optogenetics gets optimised for light engine
Swedish diode-pumped solid-state laser manufacturer cobolt has announced a modulated dual-line light engine optimised for high-end Optogenetics research applications. This version of the cobolt dual combiner offers
two emission wavelengths for light-activated proteins, 473nm (up to 50mW) and 594 nm (up to 100mW). Through the integration of a silent SrS shutter the output beam can be modulated at up to 100Hz with a very short rise time of <350μs. This can also maintain a three per cent power stability and an rmS noise of <0.3 per cent. each line can be individually addressed
Modulight extends laser family for medical applications
Finnish company modulight has announced the extension of its LimeLight product family with the introduction of the 465nm (1W) blue laser single-emitter based system for acne treatment and teeth whitening. The existing LimeLight family comprises lasers for medical, industrial and defence
surgical and X-ray alignment get visible lasers
Power Technology has launched its PnF Series green wavelength spectrum lasers for surgical and X-ray alignment applications on dark or pigmented skin. Green lasers are much more visible to the human eye than traditional red wavelength surgical lasers. The Green PnF Series can deliver an output of either 20mW or 45mW with a wavelength of

applications in the range of 465nm to 1550nm with output powers up to 1.5W. Standard products come with fibre output with an Sma- 905 connector, integrated driver and cooling controller. LimeLight systems can be controlled via a
uSb port with a standard Pc user interface or by an analogue/digital control signal directly.
