Jena, 14.05.2012

Jenoptik's Lasers & Material Processing division displays its laser sources and laser machines for innovative and efficient photovoltaic production on the Asian market. To be seen at the trade fair SNEC 2012, booth E4-275, Shanghai New International Expo Center, Shanghai, China from May 16 to 18, 2012.

"We are pleased to present our laser processing equipment to the Asian prospects at the SNEC 2012," says Dr. Thomas Fehn, Executive Vice President of Jenoptik's Lasers & Material Processing division. "Jenoptik's products for the processing of solar cells are high performers and deliver stable results in standard photovoltaic applications such as silicon ablation or laser edge isolation as well as in many modern innovative technologies."

Jenoptik's infrared disk laser with independently adjustable laser parameters for the photovoltaics

To be seen in Shanghai will be the newly introduced infrared disk lasers JenLas® disk IR50E and JenLas® disk IR70E with optimized, independently adjustable laser parameters for the photovoltaic sector. These E-version lasers (E = extended) achieve shorter pulse lengths, significantly higher repetition rates and constantly high pulse energies. Another advantage for the user is that the pulse lengths of the lasers can be adjusted independently of repetition rate and laser power. Standardized interfaces for easy integration and high control flexibility (analog, digital, software) were also an important aspect and have been realized accordingly.

The new JenLas® disk IRxxE lasers particularly meet the requirements of LFC (Laser Fired Contacts) with up to 25,000 contacts per second, MWT (Metal Wrap Through), EWT (Emitter Wrap Through) as well as LEI (Laser Edge Isolation).

Femtosecond laser for optimal use in the photovoltaic industry

Another product to be exhibited is the femtosecond laser JenLas® D2.fs. Based on the disk laser technology, the laser guarantees outstanding parameter stability and sets a new standard for laser sources of the femtosecond technology. The laser emits high pulse energies and can be operated in the high repetition range. The beam quality of M²
