The TELESIS EVCDS marker is an extremely cost effective DPSS laser based on a proven advanced Q-Switched, fiber-coupled diode end-pumped Nd:YVO4 laser platform for applications requiring high beam quality and stability. It features a dual sensor shutter safety system and its exceptional power stability at all power levels makes the EVCDS an ideal choice for engraving, annealed marking, or high speed marking on delicate and heat sensitive electronic components, thin foils and medical instruments. The EVCDS is completely air cooled with a very compact, easily integrated package requiring very little maintenance. With an expected lifetime for the 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 the laser. The compact footprint of the system allows for the easy integration into both manual off-line and automated in-line applications with Marking-On-The-Fly (MOTF)
support for high volume applications.*

SYSTEM OVERVIEW

The Telesis® EVCDS 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. The EVCDS does an exceptional job of high speed marking on delicate and sensitive electronics components and medical instruments. These characteristics make it an ideal choice for general-purpose laser marking, scribing, trimming, and other material processing applications..

The EVCDS design features a Q-switched Nd:YVO4 end- pumped laser with a remote fiber-coupled diode pump source. With an average diode MTTF of 500,000 working hours, the EVCDS offers the user “best-in class” reliability.

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

The laser marking system offers these advantages:

• Reliable,long,maintenance-freeperformance

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

• Exceptional beam quality and stable output power

• Visible (red beam) aiming diode
• Air cooling
• Thermo-electrical temperature control of the laser crystal and pump diode
• Active AOQ-switching
• Standard 115/230VAC operation
• Large digital display for marker status 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 EVCDS is available in several configurations. The system computer, required for running the Merlin® II LS software, may be an external device connected to the laser controller, or embedded within the laser controller itself. Additionally, the system may be configured to mark only stationary objects or to mark objects while they are moving (i.e., mark-on-the-fly).

The modular design allows for major components to be easily replaced and returned to Telesis if required. The basic laser system consists of the following components.

• LaserMarkingHead–containssealedresonator,beam expander, galvanometer assembly, and aiming diode.

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

• Fiber Optic Cable Assembly
• Cable Assemblies – power, control, and data cables

• Software – Merlin II LS Laser Marking Software

• System Computer – may be an external device connected to the laser controller or embedded within the laser controller itself. If external, the computer may be supplied by Telesis or by the customer.

• Monitor,Keyboard,andMouse–suppliedbyTelesis for systems with embedded computers; may be supplied by Telesis or by the customer for systems with external computers.
