JENOPTIK Laser GmbH, Healthcare & IndustryRequest Info
 
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.

GLOSSARY
beam diameter
1. Calculated distance between two exactly opposed points on a beam at a chosen fraction of peak power (typically 1/e2). 2. The diameter of a circular aperture that will pass a specified percentage (usually 90) of the total beam energy.
laser head
Contains elements which produce lasing., e.g. gain medium, oscillator mirrors as well as housing.
polarization
With respect to light radiation, the restriction of the vibrations of the magnetic or electric field vector to a single plane. In a beam of electromagnetic radiation, the polarization direction is the direction of the electric field vector (with no distinction between positive and negative as the field oscillates back and forth). The polarization vector is always in the plane at right angles to the beam direction. Near some given stationary point in space the polarization direction in the beam...
