BLADE

The BLADE-series is the one, when maximum versatility in micro/macro-material-processing will be claimed. The unparalleled characteristics in precision and repeatability owed to the innovative resonator design - generate ultra-high peak pulse output, while eliminating first pulses.

The exceptional beam-quality, combined with the short pulse duration, suits your needs in surface-ablation and –structuring or micro-drilling applications as well as all forms of marking tasks, by meaning nothing streamlines and enhances your production technology like the BLADE-series.

Advantages:
- incredible laserpower (eg. 30 watts, q-switched, 532 nm / green) even though only having an ultra small footprint. Just using aircooling (no need to use a complicated cooling-unit and/or to regulary exchange parts of the coolingsystem (for instance: ion exchangers, filters, …). Our highpower-laser is only a little bigger than an average postcard (200 mm x 200 mm). Consequently it can be very easily integrated into production lines.

- exceptional high efficiency due to fact, that the laser is operated with a special ND:YVO4-crystal (much higher gain due to the very high stimulated emission cross-section compared to a ND:YAG-crystal). Therefore our laser is ideal for generating very short pulses of only several nanoseconds at high repetitionrates. This is very important, when the heat-effected zone is supposed to be held as small as possible.

- highest stability of the excellent beam-quality in the diffraction-limited single-mode using high pulse-peak-power, no matter which frequency is used and no matter if operated in single-shot-mode or with pulserates of 1 Hz up to 500 kHz. Due to the high pulse-peak-power and the small M2<1,3, it is even possible to generate an optical breakdown (plasma in the air). Therefore our laser is also perfect for LIBS-applications.

- computer-operated change of the wavelength (for instance from 1064 nm to 532 nm or to 355 nm) using our DuoBlade.

- capability to precisely form the laser-emission using a special technique of modulation, which does not influence the quality, the form and the focus-position of the laserbeam at all (this feature is especially important when working on critical applications, such as photovoltaics and passport-production). With our modulation-technique, you can modify the energy of any laserpulse within a pulse-train. The so called “first pulse problem” is eliminated completely. Using our unique modulation-technique, you are able to reach a very high throughput even if managing complicated applications.

- compared to the wavelength of an infrared-laser (around 1064 nm) our green laser using a wavelength of 532 nm accomplishes an up to 4 times higher power density on the material while being operated at the same power-rate. On top of that, a wavelength of 532 nm is absorbed a lot better by most materials (including but not limited to: copper, brass, gold, many synthetic materials (plastics) and semiconductors) than the wavelength of an infrared laser. Consequently our laser can even be used for cutting-applications. Of course even materials as ceramics, diamonds and yet glass, can also easily be processed, using our laser. As a further consequence of the shorter wavelength compared to an infrared-laser, ultrafast scanheads using highly dynamic, small deflection mirrors can be implemented, whereby the throughput is increased while having exactly the same focus-spot on the material.

- the laserdiode used in our systems has an estimate lifetime of 100.000 hours. And in case, a laserdiode-exchange should one day be necessary, the system does not need to be sent in: The exchange can easily be done on site (you can even exchange the laserdiode yourself after having been instructed by us).

- beam-source and supply-unit can be disconnected and then combined with other units which have different characteristics (“construcition-kit”-function). Therefore (by separating beam-sourse and supply-unit) it is possible to avoid negative effects on the thermal-management (a very important feature if the laser is supposed to be integrated in an existing production-line). When being used for laser-class1-applications, our laser is superior to other lasers which lack the above-described function.

The list beneath is supposed to give you an overview over the advantages of our lasersystems, using our Blade VS30 (30 watt, 532 nm) laser-system as an example:

- 30 watt, q-switched, single-mode (M² < 1,3) / 532 nm (green), linear polarised.
- unique options of modulation (a special technique of modulation enables you to modulate every single pulse in the pulse-train).
- steady focus, no matter which power and frequency is used and no matter if operated in single-pulse-mode or with pulserates of 1 Hz up to 500 kHz.
- up to 4 times higher power density on the material while being operated at the same power-rate compared to 1064nm.
- huge variety of materials that can be marked and – depending on the dimensions of the material – also be cut: copper, brass, gold, many synthetic materials (plastics) and semiconductors, ceramics, diamonds and yet glass.
- entirely using air-cooling (and no water at all = not even a closed water-cycle).
- complete abandonment of the use of air-filters.
- highly splash-proof (if appropriately integrated).
- only using one single pump-laser-module.
- laserdiode with an estimate lifetime of 100.000 hours.
- diode-exchange can easily be done on site (by yourself after having been instructed by us).
- special YVO4-crystal-resonator-geometry (extreme high level of efficiency: up to 50 % laserpower at 532 nm in relation to the pumping power of the laserdiode.
- no “photodarkening” of the lasermedium or even it`s destruction as a result of reflections on the material.
- very small dimensions.
- very high wallplug-efficiency.
