The focal point position for cutting is typically related to the type of assist gas used for the application. Your settings may require some tweaking. Ziele. If in doubt, use the lowest power possible.

With starting values for pulse energy and peak power, the process calculator provides a tool for determining the optics configuration that will give the correct hole diameter and peak power density. What began as a tool used by Prima Power Laserdyne Applications Engineers in their CW and QCW fiber laser process development projects is now being made available free of charge to users of LASERDYNE systems.The calculator, which runs in Microsoft Excel, helps process engineers and laser system operators more efficiently develop new processes as well as better understand the likely impact of changes made to existing processes.Parameters for 2-4 kW CW fiber lasers and 3-20 kW QCW fiber lasers are available options in the ‘Laser’ menu.The calculator began as a tool used by Prima Power Laserdyne Applications Engineers in their process development projects.

Advantage Meter iPhone Android. Laser peak power scaling and beam quality improvement with Ytterbium rod-type fiber amplifiers made by powder sinter technology Dissertation zur Erlangung des akademischen Grades doctor rerum naturalium (Dr. rer. Novel architectures of Petawatt-class, high peak power laser systems that allow operating at high repetition rates are opening a new arena of commercial applications of secondary sources and discovery science.
On the other hand, an overlap as low as 50-60% can be used for applications in which speed or cycle time is the main goal.In the typical application, the final step will be to adjust the pulse width to achieve a value of average power consistent with the part geometry and precision.“The calculator will help users plan a process that will get them close before they get onto the laser machine.”A 70% overlap is generally considered a lower limit for hermetic (leak-tight) welds in pulsed laser welding.

Bestenliste. This convenient online tool will calculate what optical density is recommended for use with a laser system of a given power. The general rule of thumb is that an overlap of 75% to more than 90% should be used for applications requiring a high quality, burr-free edge finish. This convenient online tool will calculate what optical density is recommended for use with a laser system of a given power. Power Calculator. For oxygen-assisted cutting, the focal point will usually be located at the top surface of the material (Defocus = 0), whereas the focal point will be located into the material (Defocus = a negative fraction of the material thickness) for nitrogen-assisted cutting.The focused beam diameter is automatically calculated from the optics configuration and any defocus.
pulse energy (joules/volt) or peak power (volts/watt. Our divergence calculator helps you to imagine how important the divergence is. geboren am 07.04.1986 in Shanxi, China. In a previous paper, the author presented an empirically derived mathematical model of a pulse pumped laser which allowed calculation of the output energy from the laser—from the mirrors-only resonator to the fully assembled Q-switched state. It is also used to identify other laser parameters. Trainingsangebot Bekleidung Gutschein. Soon, they found themselves using it to answer questions frequently asked by users of LASERDYNE systems such as:Still wondering if you can make use of the calculator? Next, the user enters a value of peak power within the limits of the laser and the particular type and thickness of material being cut.Following this, the focal point position is specified. New coupling and loss time constant are stated. This site is home to The Evaluator – LIA's Web-based Laser Safety Hazard Analysis System. Suggested power and speed settings to give you a starting point - and a general idea of what settings to use for your circumstances. In this paper the model is developed further by deriving an expression for the peak output power.
Using the initial inputs, the calculator determines the overlap percentage and color codes the ‘Pulse overlap’ cell based on the degree of overlap.In the example pictured below, the combination of laser beam and process parameters gives an overlap of 83%, more than adequate for a leak tight weld as indicated by the green highlighted cell.Why not make use of this new calculator rather than guess at the answer or search the internet for the correct formulas?You can request your FREE desktop version of the calculator by e-mailing Also, please note that the upcoming Advanced Training class will include a session on use of the calculator for process development. This site is home to The Evaluator – LIA's Web-based Laser Safety Hazard Analysis System. It is also used to identify other laser parameters.The process is similar for cutting applications, though the range of parameters can be quite different based on the application requirements.
