Jenoptik's has introduced a new femtosecond laser, its JenLas D2.fs, which is based on diode-pumped disk laser technology, providing outstanding parameter stability. The laser's working temperature range of 15-35°C allows it to be used in most industrial environments, while offering high pulse energies of up to 40µJ at 100kHz repetition rate, and a 30-200kHz range. The beam quality of M² ≤ 1.25 is close to the theoretical limit, and pulse durations of ≤ 400fs open up new laser applications in industry.
To ensure industry capability, every laser is subjected to strict type tests to guarantee safe function under typical conditions of transportation, storage and operation. This includes climate and shock tests, noise immunity to external electrical noise and compliance with the low EMC standards for electrical noise emission. Major features include ease of integration of the turnkey laser in complex machines and plants. For example, the actuation signal can be released by software or hardware.
Due to the specific properties of the impact of ultra-short femtosecond laser pulses on different materials, new laser applications can be found. For example, these laser pulses are excellent for all material processing applications for which minimal heat effects during processing are important. Another area includes processing inside of transparent materials, such as glass, transparent plastics and transparent function layers. A third and final field of application is the selective ablation of individual layers in multiple-layer systems consisting of different materials.
