There are many mechanical and laser marking machine can be controlled ablation method Plume to remedy the problem of droplet. High repetition rate ultrafast fiber lasers provide an alternative solution. In particular, the laser pulses together forming a pulse train (bursts), each burst comprising several individual pulses, which can achieve more precise control of the heat, so that the target substance without forming large direct gasification melting drops. Proposed laser discs (Disk Laser) design effectively solves the thermal effect of solid-state lasers, solid-state lasers to achieve the perfect combination of high average power, peak power, high efficiency, high beam quality. LASYS 2012 exhibition in fiber laser marking machine, IFSW Stuttgart and TRUMPF (TRUMPF) said laser disc laser manufacturing foothold. In the automotive, marine, rail, aviation, energy and other areas become irreplaceable new processing with laser light. June 2012 in Stuttgart held lasers and material processing laser source LASYS 2012 exhibition and its related meetings, Stuttgart is the home of TRUMPF Laser Tools College is also the seat of the University of Stuttgart and the origin of the laser disc (20 the early 1990s). Disk laser is a new laser, currently on the market are rare, laser discs and production with independent intellectual property rights of the manufacturer few. Laser marking machine adjustable mirror beam expander. Laser marking machine beam expander mirror adjustments required: First, to ensure the incident beam expander to be central light well, outgoing light to be in the center of the aperture; beam expander greatly affected the quality of the adjustment has the effect of laser marking . Mainly in: a laser power down; b internal format uneven marking laser intensity; c computer software design center deviate galvo the photophysical center .... d. not play a beam expander effect. On the beam expander tube also has six adjustable screws. If the beam expander offset large, can not fine-tune the calibration, proceed as follows: first, by adjusting the three adjustment screws from the back of the laser light beam expander tube front center of the hole injection; the second step, by Three adjustable front adjustment screw so that the reflected red light and red concentric. When the adjustment to meet the requirements, you can clearly see by the large number of concentric rings return spot shines on the red laser white grating, and concentric. Because of its weak flare, during the second part is recommended in low-light environments. The third step is the first step in the process is repeated. If the beam expander offset much wholesale laser marking machine, ensuring the red laser light is collimated and coaxial with the red light, you can observe the red light is roughly from the center beam expander to enter, it is also the center beam expander In marking the software inside the box draw close to full format, continuous high-speed, beat in a flat metal surface laser marking machine, under normal circumstances should be translucent pieces evenly on all sides energy laser marking machine, if uneven trimming beam expander , remember a few laps rotation after trimming if energy difference greater need of each side in the opposite direction to adjust, and ultimately achieve each side evenly.
