The Lasers & Material Processing department at Jenoptik will reveal the latest developments made by the company in the field of laser sources including the JenLas Disk IR70 E and the JenLas Disk IR50 E at the European Photovoltaic Solar Energy Conference and Exhibition held in Hamburg, Germany from 5 to 8 September, 2011.
The JenLas Disk IR70 E and JenLas Disk IR50 E are the latest additions to Jenoptik’s range of infrared disk lasers. The Extended (E) series lasers are designed to achieve higher repetition rates, high pulse energies and shorter pulse lengths. The laser sources feature optimized and separately adjustable laser parameters, which can be easily configured by the user. This feature allows independent adjustment of laser power and repetition rate needed to determine the laser’s pulse length.
Designed with safety in mind, the lasers have been designed with an intelligent laser control. For high control flexibility and easy integration, the JenLas Disk IR70 E and JenLas Disk IR50 E feature standardized interfaces. The lasers are compatible with the latest technologies in the photovoltaic industry which includes laser fired contacts(LFC) achieving up to 25,000 contacts every second. LFC is an alternative technology to solar cell backside contacting causing an increase in cells’ electrical efficiency.
The JenLas Disk IR70 E features a laser power of 65 Watt, pulse energy of 7 mJ while the JenLas Disk IR50 E features a laser power of 45 Watt and pulse energy of 5mJ. Both the E-series laser sources have a 300 kHz repetition rate and an infrared lasing wavelength of 1030nm.
