Coherent Inc. of Santa Clara, Calif., has acquired Innolight Innovative Laser and Systemtechnik GmbH and Midaz Lasers Ltd. to provide core technology for an emerging class of low-cost commercial subnanosecond pulsed lasers for microelectronics manufacturing. It paid $18 million for the privately owned Innolight of Hannover, Germany. The business will operate as part of Coherent’s existing German business unit. A spinout from the Photonics Group at Imperial College London in the UK, Midaz has developed a range of diode-pumped solid-state lasers for micromachining applications, including medical device manufacturing. The purchase price for Midaz was $3.7 million.
- A device that enlarges and strengthens a signal's output without significantly distorting its original waveshape. There are amplifiers for acoustical, optical and electronic signals.
- A contraction of "excited dimer." The term refers to an excited species made by combination of two identical atoms or molecules, one of which is excited and one of which is at a ground state.
- pulsed laser
- A laser that emits energy in a series of short bursts or pulses and that remains inactive between each burst or pulse. The frequency of the pulses is termed the pulse-repetition frequency.
- solar cell
- A device for converting sunlight into electrical energy, consisting of a sandwich of P-type and N-type semiconducting wafers. A photon with sufficient energy striking the cell can dislodge an electron from an atom near the interface of the two crystal types. Electrons released in this way, collected at an electrode, can constitute an electrical current.
