J Series / Ultrafast Laser Micromachining System

Practical Ultrafast Laser Machining is here

Key Benefits

Ultrafast laser micromachining using picosecond or femtosecond lasers can be used for the most challenging applications. The J Series combines the precision of ultrafast laser micromachining with Oxford Lasers’ high stability granite structure and intuitive control software.

Picosecond Laser Micromachining

Picosecond laser micro machining utilizes a very short pulse laser (typically 8 to 12 ps duration), to prevent the formation of a heat-affected zone. Very high accuracy micro-hole drilling and micro-cutting can be performed in almost any material. The lack of thermal damage makes the J Series particularly useful for machining heat sensitive materials.

Femtosecond Laser Micromachining

For the ultimate in ultrafast machining a femtosecond laser micromachining system can be used. The 20-fold reduction in pulse duration relative to a picosecond system gives some advantages in terms of material interaction.

The very high peak power density that can be achieved using a picosecond or femtosecond laser means that these types of laser can be used to machine otherwise transparent materials such as silica or sapphire. Non-linear absorption enables the light to interact with transparent materials, causing very strong, extremely localised heating and ablation. In addition the strength of the laser ablation process results in a very low debris process.

The J Series is also a very powerful micro-milling tool. The very high peak power density leads to a very controlled micro-ablation process ideal for micro-milling. As described above, this can be particularly advantageous when milling transparent materials such as quartz / fused silica or sapphire.

The Class 1 enclosure, single-interface computer control and turn-key operation make this system easy and safe to operate.

A vibration isolated granite bed offers ultimate stability and helps guarantee maximum repeatability and accuracy in the parts produced. With 300 mm X-Y travel and 150mm Z-travel, the system is able to machine large numbers of parts (or small features in large parts) and the on-axis vision system simplifies alignment and allows the operator to check their work.

If required, we can add trepanning heads, longer travel stages, galvo-scanners, taper control systems, rotational stages, height/depth sensors, auto-focus and auto-alignment, motorised attenuators, temperature stabilisation and fume extraction.
