Clamping ™ Technology

Solder-free laser bar mounting

Patent EP1341275B1 – For exclusive use of Monocrom S.L.

While soldered bars present a serie of problems as thermal expansion mismatch, high temperature process, fatigue effect with consequient lifetime reduction, our Clamping technology overcomes all of these troubles thanks to the total elimination of the soldering process.

The bars are clamped between two electrodes like a sandwich

The process is performed at room temperature avoiding stress coming from the different thermal expansion of the electrodes and the bar. The reduction of the mechanical stress minimize the smile effect, improving laser beam quality and considerably increasing usefull life-time of the laser diode.

No “Smile” Effect

Smile is not an issue when clamped bar mounting is used.

Clamped bar “smile” = 0,1um

Large storage Clamping

Large operation and storage temperature range

At high temperature, the solder outgassing can produce the contamination of the laser bar. When clamped-mounting of bars is used, operation and storage temperature can increase.

Storage temperature: (60ºC,+85ºC)

The process is performed at room temperature avoiding stress coming from the different thermal expansion of the electrodes and the bar. The reduction of the mechanical stress minimize the smile effect, improving laser beam quality and considerably increasing usefull life-time of the laser diode.

High cooling efficiency

The non-soldering technique allows the use of electrodes with high thermal conductivity. Furthermore both anode and cathode electrodes act as heat sinks. There is no thermal barrier between the laser bar and the electrodes.

 High reliability

Clamped laser bars (single or stacked) shows excellent reliability operating in all possible operation modes, from very short pulses at high repetition rate, to CW conditions.

The process is performed at room temperature avoiding stress coming from the different thermal expansion of the electrodes and the bar. The reduction of the mechanical stress minimize the smile effect, improving laser beam quality and considerably increasing usefull life-time of the laser diode.
