with the Coherent ModeMaster PC is to align the
system's optical axis with that of the input laser beam.
This is necessary in order to achieve accurate results.
Two tools are built into the product to enable simple,
rapid alignment to a very high degree of accuracy. The

first reported the effectiveness of this method. Zheng et al.  reported that their VBGECDLA reached 0.24 nm FWHM bandwidth and 20 W output power.
In this paper, we report a unique VBG-ECDLA where the DLA's…

the entire laser cavity is contamination-free by design
and virtually impervious to damage and aging. This is
in stark contrast to most other lasers where designers
(and often end-users) have to worry about maintaining
optical alignment and laser cavity cleanliness.…
…the solid-state pump and the Ti:S lasers were integrated in a compact and fully sealed laser head, were fully controlled by a single computer interface or push-button menu. With no need to physically align, clean, or manually adjust the laser optics, even a laser novice could confidently use these…
…accurately align the cut pattern to the
material. This enables accurate cutting regardless of material orientation in the machine, thus eliminating the
need to position material with high precision and minimizing overall process time.
This system also uses sealed CO

easy to align and durable in industrial and commercial manufacturing processes. There is no alignment needed with
respect to the locking mechanism. The only criteria for aligning the VHG-FAC are the…

Optimized high-power laser beam delivery involves careful consideration for loss elements such
as misalignment or back reflections, maximization of BPP and precise factory alignment to ensure
plug-and-play simplicity and long service life.
