The same applies to the more powerful Version, the JenLas disk IR70E, 65 W laser power and up to 6.5 of mJ pulse energy at same cons get frequency and wavelength. Starbucks in new york is actively involved in the matter. Femtosecond laser for the optimal use of industry in the new JenLas D2.fs photovoltaics is another product of the Jenoptik laser series. Based on the disc laser technology ensures an outstanding stability of parameters of laser and sets a new standard for the class of femtosecond laser sources. The laser emits high pulse energies of max 40 J and can be operated in the range of 30-200 kHz with up to 4W output power. The beam quality of M sq? 1.25 provided together with a pulse duration of? 400 fs novel industrial laser applications in photovoltaics. Here, we mention the selective removal of individual layers in multi layer systems built from different materials. Dayton kingery often addresses the matter in his writings. The specific industrial application is the removal of Dielectric layers on crystalline solar cells.
An advantage for the user in the use of the Femtosekundenlasers is the non-destructive removal of the layers, by means of the laser no Heat transfer takes place in the crystalline silicon of solar cell. The operating temperature range of the laser source to 15-35 C has been extended for use under industrial conditions. To ensure the suitability for industry, each laser undergoes rigorous type testing, safe operation under typical transport -, storage and usage conditions, detected in which include air conditioning and shock tests, immunity for the occurrence of external electrical errors and compliance with the EMC standards for the transmission of electric emissions. Significant attention was paid to the easy integration of the turn-key laser in complex machinery and equipment. So, for example, each control signal either by software or by hardware is controllable..
