Ultrafast Pump-Probe System

The Minnich Lab is equipped with an ultrafast pump-probe system centered around a Coherent Mira oscillator. Together with a delay stage, this system is capable of resolving ultrafast phenomena with subpicosecond time resolution and up to 13 ns total delay time. The system of also capable of modulated CW operation at frequencies up to 25 MHz. Using continuous flow cryostats we can access temperatures from 3-500 K. The Minnich Lab is also fortunate to have the use of an asynchronous optical sampling (ASOPS) system, courtesy of Professor Geoff Blake. This system consists of two synchronized ultrafast oscillators at slightly different repetition rates, with a function similar to a stroboscope. Ultrafast phenomena are stretched out in time and can be recorded with a low bandwidth oscilloscope.
