Design & Control Laser Processing At Your Fingertips

Laser processing systems are highly flexible and efficient for a wide range of applications. The key to getting the system up and running fast and easily is heavily dependent on the system controls and user interface. Mixing and matching laser system controllers and UI software can present a plethora of compatibility and integration issues that cause build delays and frustration for operators.

Sub-System Featuring a CO2 Laser and Scan Head

CO2 lasers are widely employed in various applications, including marking & coding, cutting, drilling & perforating and ablation, as well as industries ranging from converting to 3D Printing, where high speed and accurate manipulation of the laser beam is crucial. The laser source is usually selected for its pulse performance, optical output power, and wavelength, while the scan head is selected for its field & spot size, speed, and accuracy specifications. Thus, while each component is chosen for its individual performance characteristics, achieving optimal performance from the combined system presents a unique challenge for machine builders and laser integrators.

 

 

This paper delves into the intricacies of integrating CO2 lasers and galvo scan heads to achieve complementary performance.

What Are Ultrafast Lasers Used For?

Over the last thirty years, ultrafast laser development has continued to generate interest and activity. Researchers and system designers developed multiple techniques to generate ultrashort laser pulses over the years. Accessibility to ultrafast lasers enabled investigations into a broad range of physical, chemical, and biological phenomena using ultrafast optical spectroscopy. Additionally, investigations of the practical applications of ultrafast laser technology progressed.

 

 

Ultrafast lasers can also be useful for requirements in the automotive industry. This includes the structuring of small grooves into the surface of the cylinder wall of a combustion engine. This ensures a thorough distribution of lubricant along the piston wall to minimize friction loss.

Analog vs. Digital Galvanometer Technology – An Introduction

When designing a new laser application with beam deflection units, most engineers will choose the optical design (mirror size, coatings, mirror material) with great care. This makes sense as the effective focal length, spot size and the power handling the system are all crucial. However, choosing the right galvanometer technology is just as important for the overall achievable performance of the application.

 

 

 

In this white paper, we discuss the advantages and disadvantages of analog galvanometers and servo units and, in particular, hybrid solutions using digital servo technology with analog galvanometers. Influences of the respective technology on achievable speeds, accuracies and integration hurdles are examined.

A Very Brief Guide to Femtosecond Lasers

Lasers emit light either continuously or in a train of pulses. Under the heading of ultrafast lasers falls a certain group of lasers that produce picosecond, femtosecond or even nanosecond pulse durations at different repetition frequencies. Within this group, femtosecond lasers emit optical pulses with a pulse duration in the domain of femtoseconds (1 fs = 10-15 s) typically ranging between a few femtoseconds to hundreds of femtoseconds.

 

 

This blog explains femtosecond lasers and their usage.
