A laser head for the MDL 300 at 485 nm is now available.
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 ultrafast 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.
