Diode laser PicoQuant

The MDL 300 modulated diode laser driver provides modulation frequencies up to 1.8 GHz and generates sinusoidal waveforms for 6 predefined frequencies. It is an ideal ultra-fast excitation source for phase modulation fluorescence lifetime measurements in a compact set-up. The MDL 300 consists of a driver / controller and interchangeable laser heads for applications up to 1.8 GHz. In addition, pulse mode is possible by overdriving the modulation level.

The MDL 300 features easy-to-use controls for modulation frequency and laser power level. Predefined modulation frequencies of 250, 100, 25, 5, 1 and 0.25 MHz are derived from the internal crystal oscillator. Alternatively, the laser intensity can be modulated by either an external RF or DC/LF signal. The maximum frequency is dependent on the laser wavelength (see the specifications for the available laser heads). A Sync output allows the modulation signal to be monitored externally.
