Jenoptik Laser GmbH’s Lasers and Material Processing division has introduced the JenLas disk IR70 infrared disk laser, which meets the requirements of the new technologies in the field of photovoltaics, such as metal wrap-through and emitter wrap-through at up to 20,000 holes per second. Output power is >65 W at 30 kHz, polarization is linear, beam quality is M2 ≤1.2, and beam diameter is 1.4 mm. Pulse energy is >7 mJ at 8 kHz, pulse repetition rate is from 8 to 30 kHz, and typical pulse length is from 650 to 1700 ns, depending upon the repetition rate. The laser head measures 865 x 340 x 184 mm and weighs approximately 50 kg. The laser covers a wide range of applications in the infrared wavelength range at 1030 nm, and the 65-W system is suitable for laser drilling of the silicon wafers that enable efficient production of back-contact solar cells.
