Quantum cascade laser

CW operation mode

QC lasers from Alpes Lasers SA are mounted on special carriers (NS or ST), which requirespecial handling and definition of geometrical orientation. A CW QCL is about as sensitive to electrical surges and instabilities as a conventionalbipolar laser diode (telecom NIR laser). It is necessary to use a good quality power supplyto ensure:• current onset is formed by well controlled ramps without surges• current and voltage compliance can be precisely set (1mV/1mA)• current and voltage are stable within 0.1%We recommend precision laser diode current sources such as the ILX Lightwave LDX-3232.
