Universal talents: High performance laser modules in the match format

The FBH places its miniaturized sources of laser beam into the center, which are suitable for a multiplicity of applications on the lasers World OF Photonics, from the material processing to display technology with compact sources of laser beam in the matchbox format opens the Ferdinand brown institute, Leibniz institute for very high frequency technology (FBH) various operational areas. The flexible � Jacks of all trades � let themselves be optimized on the respective requirements, have the lasers in material analytics, the display technology or the material processing to fulfill. The manufacturing of all lasers at the FBH of the epitaxy of the function layers over the wafer structuring and the production of the laser chips up to the structure and assembly of the elements takes place in pure areas of different pure classes of area. That is called each laser goes through pure space laboratories with pure classes of area up to the ISO 5 (lithography). The modules consist of several opto-electronic semiconductor chips (diode lasers and� - amplifiers) and on it co-ordinated gallium nitride transistors. All chips were developed at the FBH and to be based on the comprehensive know-how of the institute during the semiconductor technology and chip development. Besides hybrid integrated micro optics and nonlinear crystals form the jet and/or transform the wavelengths into the blue and green spectral region. In this spectral region they reach now for the first time achievements over 1,5 W with good radiation quality. By the simple frequency doubling in � the single passport � - procedures can be particularly compactly realized it. They are suitable for applications, which are called intoxication poverty � if possible few spurious signals � and require a fast modulation. Efficient, pulsed sources of laser beam offer high flexibility besides present the FBH diode laser, which is preferably used due to their flexibility in laser systems for the material processing. Also mobile eyelid acre systems for close range can profit from the efficient, compact diode lasers. In addition a again developed, miniaturized and pulsed radiation source with 10 HP belongs 100 LV to pulse width and defined recurrence rates in kHz and MHz range. This presents the FBH also to the accompanying specialized conference. With hybrid integrated amplifiers it reaches maximum performances up to some 10 W.� The FBH with for the first time presented profit-switched 1064 Nm DFB laser diodes with integrated electronics shows further flexible sources of light for the time intervall 1-100 LV in the Butterfly housing. Without amplifiers their pulse achievements lie with 1,5 W in the time intervall 1-10 LV. Picture:� HP source of light with integrated pulse picker (Ferdinand brown institute)
