Paper Abstract

Within the last ten years, ultrashort pulsed lasers have developed from complex scientific devices to reliable industrial tools for various applications. MOPA systems with fiber amplifiers offer an excellent combination of small size, reliable design and flexible parameters. However, their power and more specifically pulse energy levels could not reach the high level of other laser designs based on disk or rod amplifiers. In the latest development generation of TRUMPF’s TruMicro 2000 series, we present an all-fiber ultrashort pulse laser with a maximum pulse energy of 100 µJ based on industrial grade technologies. The high energy level allows for efficient frequency conversion to a wavelength of 515 nm which is beneficial for numerous applications. Furthermore, the linear amplifier concept combined with intelligent electronics and software allow for flexible adaption of parameters: The laser is equipped with a sophisticated pulse-on-demand function that allows variable pulse picking from the seed frequency of 50 MHz. This bears the challenge of fluctuating pulse ensures which is overcome by a combination of measures that ensure constant pulse energies even with variable pulse distances. As a result, the laser pulses can be synchronized to external trigger signals with a time jitter as low as 30 ns. Additionally, the TruMicro 2000 offers a flexible burst mode up to 8 pulses in one burst and the pulse duration can be changed continuously from femto- to picoseconds. With a newly patented technology, the full sweep from 300 fs to 20 ps is done in less than 500 ms without any influence on beam parameters.
