ABOUT THIS ITEM

At the heart of the EV25DS marking system is our air cooled, high power, industrial grade, diode-pumped, solid- state vanadate laser. It is designed to operate in the harshest of environments. With a pump diode MTTF of 250,000 hours, it will be able to maintain a peak performance for many thousands of 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 pro- vides the 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 fine detail 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 resolu- tion 2D codes, and can produce unique color marks on various metals.

SYSTEM OVERVIEW

The Telesis® EV25DS is an advanced, fiber-coupled diode pumped solid state (DPSS) laser marking system. The laser beam and Q-switched pulse characteristics are optimized for applications that require high beam quality and stability. In addition, the EV25DS offers extra power and speed for precision marking and material processing applications. Its short pulse width and extremely small spot size provide high resolution marking with minimal heat impact to surrounding areas. These characteristics make it an ideal choice for general-purpose laser marking, scribing, trimming, and other material processing applications.

The EV25DS design features a Q-switched Nd:YVO4 end- pumped laser with a remote fiber-coupled diode pump source. With an average MTTF of 250,000 working hours, the EV25DS offers the user “best-in class” reliability.

The robust mechanical and optical design allows the Telesis EV25DS to operate in an industrial environment where shock, vibration, and dust are a concern.

The laser marking system offers these advantages: 

• Reliable, long, maintenance-free performance 

• Compact size and modular construction
• Remote, fiber-coupled pump diode

• Exceptional beam quality and stable output power 

• Visible red aiming diode
• Air cooling
• Thermo-electricaltemperaturecontrolofthe laser crystals and pump diodes
• ActiveAOQ-switching
• Standard 115/230VAC operation
• Largedigitaldisplayformarkerstatus,settings,and error condition monitoring
• Key switch, Laser Off button, interlocked safety shutter and emission indicators
• DoD-compliant Unique Identification (UID) marking

SYSTEM CONFIGURATION

The EV25DS is available in two configurations: one for marking only stationary objects, another for marking objects while they are moving (i.e., mark-on-the-fly operation).

The basic laser marking system consists of the following components:

• Laser Marking Head–containssealedresonator,beam expander, galvanometer assembly, visible red aiming diode

• Laser Controller – contains pump diodes, RF driver, and other electrical components

• Fiber Optic Cable Assemblies

• Cable Assemblies – power, control, and data cables

• Software – Merlin®II LS Laser Marking Software

• System Computer, Monitor, Keyboard, Mouse–may be supplied by Telesis or by customer

The modular design allows for major components to be easily replaced and returned to Telesis if required.
