The TELESIS EV15DS and EV10SDS markersare based on advanced Q-Switched, fibercoupleddiode end-pumped Nd:YVO4laser technology.The outstanding beam quality of theselasers makes them superior to all other markers ofequivalent power for high resolution and high speed marking.Additionally, the shorter pulse widths and high peak powersof this marker makes it the preferred choice for challenging marking applications on silicon orheat sensitive materials such as plastics or thin foils. The smaller spot size and extended depth offocus allows these lasers to mark much more highly irregular or curved surfaces than fiber lasers.They are air-cooled and an excellent choice for high speed Marking-On-the-Fly applications aswell. With an expected pump diode MTTF of over 250,000 hours for the EV15DS and 500,000hours for the EV10SDS, system down time is dramatically reduced. Diode replacement can becompleted quickly and the fiber coupled diode design liminates the need to re-align the lasermarker. The marker’s modular design, housing the diode in the laser controller, eliminates a largeheat source from the laser insuring maximum stability as well as the need for water cooling.

At the heart of the EV25DS marking system is our air cooled, high power,industrial grade, diode-pumped, solid state vanadate laser. It is designedto operate in the harshest of environments. With a pump diode WTTF of250,000 hours, it will be able to maintaina peak performance for many thousandsof hours of maintenance-free operation. The EV25DS offers distinct advantages over fiber lasers and other solid state lasers due to its superior beam quality, providing smaller focused spot sizes and a longer working depth of field than competing lasers. The EV25DS providesthe strength to tackle metals such as stainless steel, cobalt, and titanium, as well as provide the high marking speeds required for marking-on-the-fly (MOTF). It also has the ability to do finedetail work, trimming, edge heat treating, and even marking delicate materials like plastics, foils,and labels. It produces superb annealed marks that stand up to the harshest of tests, high resolution 2D codes, and can produce unique color marks on various metals.

The EV40 is a high throughput laser marker featuring a Q-switched Nd:YV04diode pumped, aircooledlaser design with high speed digital galvo scanners. This laser provides high quality laserbeam characteristics including a long focal tolerance combined with up to 2mJ pulse energies andhigh average powers at 1064nm, allowing these systems to achieve high-speed, rapid deep markingof metals or composite materials on flat and curved surfaces and offers the user best-in-classreliability with a low cost of ownership. In addition, the integrated proprietary graphical laser softwareand optimized electronics make these systems the best solution for many high speed markingon the fly (MOTF*) applications. The robust mechanical and optical design allows these lasersto operate without any chiller in anindustrial environment where shock,vibration, and dust are a concern whilemaintaining stable output power andan expected diode MTTF of 75,000hours. The small footprint allows foreasy integration into manual off-lineand automated on-line configurations,making it ideal for a wide range of industrialmarking applications.

The TELESIS EVC marker is an extremely cost effective DPSS laser based on aproven advanced Q-Switched, fiber-coupled diode end-pumped Nd:YVO4 laser platform for applications requiring high beam quality and stability. Its exceptionalpower stability at all power levels makesthe EVC an ideal choice for engraving,annealed marking, or high speed markingon delicate and heat sensitive electroniccomponents, thin foils and medical instruments. The EVC is completely air cooled with a verycompact, easily integrated package requiring very little maintenance. With an expected MTTF forthe pump diode of over 500,000 hours, down time is dramatically reduced. Because of the modular fiber coupled design, diode replacement can be completed quickly with no need to realign thelaser. The compact footprint of the system allows for the easy integration into both manual off-lineand automated in-line applications with Marking-On-The-Fly (MOTF) support for high volume applications (*MOTF Version available at additional charge)
