Lambda Physik introduces USP Technology- Uniform Side Pumping Technology* for its Gator Series of diode pumped solid state lasers. USP Technology guarantees the long-term stability of the laser beam intensity distribution. The beam parameters stay constant throughout the lifetime of the laser head, which greatly simplifies process control and allows for excellent stability of the micromachining process.

Gator's high peak power/short pulse durations are essential for high quality, high aspect ratio microdrilling and micromachining of hard materials. The entire series produces diffraction limited TEM00 beam, with M2 <1.2, allowing for excellent beam focusability, and depth of focus. The combination of a diffraction limited Gaussian beam profile and short pulse length allow for drilling high aspect ratio holes, yielding low heat affected zones with exceptional surface quality, roundness and taper tolerances.

This series has been designed especially for micromachining of hard materials including drilling through holes, cutting and slotting. Of particular importance is the ability to drill blind holes and slots in the hardest materials including diamond, silicon, sapphire, ceramics and steel. Features below 10 micron can be produced with good surface finish. Typical examples are: Via drilling in silicon, silicon wafer dicing, sapphire wafer dicing, fuel injector nozzle drilling and stent cutting.

The Gator Series lasers adapt well to OEM and end user applications because they are easy to interface and designed for 24-hour production demands. Featuring a hermetically sealed laser head, RS 232 function control for complete hands-free operation, and remote/removable supply unit, these lasers deliver exceptional up-time performance.
