The joint project ProFIT 10156307 „LaMIK – Komponenten und Verfahren für die Laser-Mikrobearbeitung“...

supported by EFRE and the city of Berlin, has demonstrated very successful improvements in the development of ultra-compact, efficient, high-power solid-state laser systems at COMPACT LASER SOLUTIONS. The jiont project was supported by the LMTB (Laser- und Medizin-Technologie GmbH, Berlin) in proved the high utlizability of the new laser systems for the efficient, high-quality micro-machining of different metals and glasses at 532 and 355 nm.

The worlds` smallest high-power-laser (CONQUEROR 532_14VSP) meets the world`s largest high-power-laser (NIF)...

NIF is by far the worlds´ largest laser: It´s 192 intense laser beams are capable of generating nearly two million joules of laser energy in billionth-of-a-second-pulses!

Next to running many other interesting experiments, scientists at NIF are trying to produce fusion ignition with this gigantic laser. NIF is operated by Lawrence Livermore National Laboratory for the US Department of Energy`s National Nuclear Security Administration.

It took some time to get permission to publish the photos of the event. On the photos below you can see Dr. Bruno Van Wonterghem, NIF Operations Manager, unpacking and inspecting the first CONQUEROR 532_14VSP.



By far the smallest 532nm-laser in this powerclass worldwide!

14W @ 50 kHz (12ns), TEM00 (M² < 1.2), 7ns minimal pulsewidth, enormous pulse peak power, pulse peak power control, 1Hz - 500kHz, highest efficiency, entirely aircooled and can even be operated battery-powered.

CLS completes it`s productportfolio of Q-switched DPSS-marking- and micro-mechaninglasers introducing the new CONQUEROR-series

CLS completes it`s productportfolio of Q-switched DPSS-marking- and micro-mechaninglasers introducing the new CONQUEROR-series

Due to the fact that an average power-output of 5 watts combined with a high pulse-peak-power is sufficient for many...

...applications, CLS decided to introduce the new CONQUEROR-series in addition to their more powerful BLADE-series (up to 75 watts).

Like the BLADE-series the CONQUEROR-series are also solely air-cooled. CLS will present the CONQUEROR-series for the first time at the Laser World of Photonics 2011.

Compared to the usual lasers including fibrelasers the CONQUEROR-series don`t only mark common materials but also copper, gold and glass (including in-glass-engraving) in excellent quality. Even on synthetic materials / plastics the CONQUEROR-series in most of the cases provides much better results then IR-fibrelasers.

For the simple reason that the CONQUEROR-series offer smaller spots, the typeface of micromarks is a lot more accurate. Moreover many synthetic materials an semiconductors react better when using a wavelengh of 532 nm, which results in a better result and/or colourchange.

With the CONQUEROR-series CLS has lauched a lasersystem with a very small footprint which is privileged for the integration in machine-parcs and in workstations in which a very small environment is found.

Next to the configuration with a wavelength of 532 nm a configuration with a wavelength of 1064 nm is also available. Striking is the price: The sophisticated lasersystem made in Germany combined with a high-speed-scanner is offered at a very competitive price.

...switching to frequency-doubled mode (532 nm) in an option to other lasers also used in LIBS and Raman spectroscopy.

The published article: ’Assessment of suitability of diode pumped solid state lasers for laser induced breakdown and Raman spectroscopy’, by: Marek Hoehse, Igor Gornushkin, Sven Merk and Ulrich Panne, available at JAAS (Journal of Analytical Atom Spectrometry,, 2011, Advance Article), provides the detailed content. (

In the following we cited some extracts of the paper:

“…following the development of laser technologies: from microchip and powerchip lasers with only 10mJ and 50 mJ of the pulse energy, correspondingly (model JDSUniphase, Nanolase, Meylan, France), to recent DPSS lasers with more than 1 mJ of the pulse energy and 25W of continuous power (Blade YVO4IR_25, COMPACT LASER SOLUTIONS, Germany). This pulse energy is sufficient to breakdown virtually any material by focusing the laser with conventional optics. The high repetition rate provides such a large mass ablated that LIBS with DPSS lasers can outperform LIBS with FLPSS lasers even when the latter is operated in a double pulse mode.…

We demonstrated that DPSS lasers present a viable alternative to lasers typically used in LIBS and Raman spectroscopy. They offer the distinct advantages of low cost, compact size, small weight, and high durability. Their robustness and long operational lifetimes are well suited for heavy-duty industrial applications. In particular, we demonstrated that LIBS with the DPSS laser provides the competitive performance as compared to conventional FLPSS-LIBS. Despite a short plasma lifetime which limits a number of detectable photons, the high repetition rate overcomes this drawback and enables the detection of thousands of laser-induced plasmas per second. The high ablation rate results in LODs in the lowest ppm range that are among the best LODs for LIBS and can easily compete with the performance of double pulse LIBS…. “

50 years after it's invention the worlds first laser shines again for the very first time ever in Germany

50 years after it's invention the worlds first laser shines again for the very first time ever in Germany

In celebration of the 50th anniversary of the laser - one of the most epoch-making innovations of our century – Andreas Kuntze, the founder...

...of COMPACT LASER SOLUTIONS in Berlin, succeeded in bringing the worlds' first laser to the capital of Germany.

Kathleen Maiman herself presented the very first laser - which Theodore Maiman had invented on June 16th, 1960 - to public in the facilities of COMPACT LASER SOLUTIONS in Berlin.

Andreas Kuntze professionally cleaned the 50 years old ruby-crystal and carefully re-adjusted the electrodes. After he had made sure, that the system was in a safe condition, he fired the laser.

It was overwhelming to imagine that the bright dark-red laserspot that we saw, was exactly like the one Theodore Maiman created 50 years ago for the first time ever. None of us may fathom what kind of emotions excited in him upon this occurence at that time.

Earlier this June, France had appreciated the 50th anniversary of the invention of the laser by celebrating the event under the patronage of Nicolas Sarkozy in the Palais du Louvre in Paris with Kathleen Maiman as a guest of honour and several nobelprice winners and other important personalities.

...small footprint design. Just using air cooling (no need to use a complicated cooling-unit and/or to regulary exchange parts of the cooling system (for instance: ion exchangers, filters...).

It should also be mentioned, that due to the fact, that no liquids are used at all in our coolingsystem, the risk of the occur of leakages and therefore the risk of damaging the laser-source and other expensive repair-jobs caused by leakages is eliminated completely.

Our highpower-laser is only a little bigger than a typical postcard (200 x 200mm). Consequently it can be very easily integrated into production lines.
