Lumera Laser has introduced the Blaze high-performance nanosecond laser.

Spotlock pumping technology gives the Blaze laser excellent beam characteristics even at high average power and repetition rates.

Spotlock guarantees high beam-pointing stability for precise machining of various materials.

It minimises thermal effects in the laser crystal, which usually negatively affects the laser performance and stability of high-power laser systems.

As a result, compared with conventional technologies, the lasers achieve a higher performance and improved beam-control quality.

Spotlock enables the spot size and the corresponding focal position to remain constant over the entire repetition range.

When changing the process parameters, no adjustments outside of the beam source need to be made, avoiding costly set-up times.

For the processing of materials that exhibit poor absorption in the infrared spectrum, Lumera Laser provides a frequency-doubled version of the Blaze.

The high-energy version Blaze-HE produces – particularly at low repetition rates – pulses with ultra-high energy at a constant high beam quality in the TM00 mode.

The Blaze LP (long pulse) is a high-power laser developed for the solar industry.

With EWT (Emitter Wrap-Through) solar-cell technology, contacts are moved to the back of the modules so that they do not shade the solar cell; this increases the efficiency by one third.

For this application, conventional laser systems produce from 3000 to 5000 holes per second.

Due to the longer pulses, the Blaze LP drills more than 10,000 holes per second with maximum precision, at a wafer thickness of 120 microns.

This allows the required high throughput at a consistently excellent quality, resulting in a significant cost advantage in this application field.

All Blaze series lasers can be run in three modes of operation to optimise the process parameters within each application.

In the E-Max Mode, the Blaze is operated at maximum pulse energy.

In doing so the energy increases towards the low-pulse repetition rates.

The E-Lock Mode generates pulses with constant energy regardless of the repetition rate.

This enables the drilling of holes at defined intervals during the acceleration and deceleration phase of a scanner.

In the E-Free Mode, the operator can freely choose the pulse energy of each individual pulse.

Through these degrees of freedom, the laser can be optimised quickly for any specific application.

Blaze lasers can be customised to individual specifications.

LUMERA LASER develops / manufactures picosecond lasers for micro-processing.
LUMERA LASER pioneered this technology, and is the clear market leader in terms of market share, technology and reliability.

These ultra-short pulse lasers offer a new quality in laser micromachining by 'cold' ablation, by removal of any material.
A single laser pulse will remove in the focus spot (typically1-50µm dia.) a thin material layer (20-200nm), without thermal side-effects like burrs and micro-cracks. Up to 1 mio pulses per second can act, so that 6-60mm³/min can be ablated.
The proper overlap of the pulses (controlled by galvos) will define the structure; scribe, cut, drill, or produce a 2.5-D form into any material directly from CAD file.
The investment for such laser is in the order of 100-250k€, the TCO per min in the range of 12-20 Cent per minute only.
Industrial picosecond lasers are new universal tools for micro-processing of any material (!) without mechanical contact/force, without wear and tear and without thermal damages.
There is a wide range of applications in semicon, LED making, PV, display tech, micro tool manufacture, micro-fluidics, bio-med, automotive, aerospace, printing, etc.

LUMERA LASER runs an experienced app lab to demonstrate a solution for your application.
