摘要:
The present invention is directed to opening a spring roll pack in a controlled manner. A support surface is provided that is positioned to support the spring roll pack. A compression mechanism compresses the spring roll pack. As the spring roll pack is compressed, the spring roll pack is rotated while an accumulator winds wrapping material of the spring roll pack.
摘要:
In a surface emitting semiconductor laser comprising a semiconductor chip (1), a first resonator mirror (4) and at least one further resonator mirror (8) which is arranged outside the semiconductor chip (1) and forms with the first resonator mirror (4) a laser resonator having a resonator length L and a pump laser (10) which, for optically pumping the semiconductor laser (1), radiates pump radiation (14) having a pump power into the semiconductor chip (1), the pump power is modulated with a modulation frequency fp and the resonator length L is adapted to the modulation frequency fp.
摘要:
Circuit arrangements for the operation of a pulse laser diode and methods for operating a pulse laser diode include a current source to supply a direct current to the pulse laser diode. The circuit arrangement can provide operation of the pulse laser diode that can be stable and without unintentional shifts in wavelength.
摘要:
A laser diode component comprising a laser diode bar on which a specific operating voltage is impressed during operation and with which a bridging element is connected in parallel, which bridging element is in a current-blocking state when the specific operating voltage is impressed on the associated laser diode bar and which bridging element changes over to a current-conducting state as soon as the voltage drop across the laser diode bar exceeds the operating voltage by a predefined voltage value. A circuit arrangement comprising a plurality of such laser diode components which are connected in series is furthermore specified.
