The Cavity Dumper Kit is an acousto-optical switch that is integrated in the cavity of a mode-locked laser system for the reduction of the system's pulse repetition rate (cavity dumping). Unlike pulse pickers, which are placed outside the cavity, the intra-cavity operation increases the pulse energy to a multiple of the energy that is reached with simple mode-locked operation of the system. This makes it particularly relevant for nonlinear optical processes like SHG (Second Harmonic Generation) and THG (Third Harmonic Generation).
- Generation of powerful laser pulses
- Fast risetimes
- Tunable phase shift
The Cavity Dumper Kit consists of an acousto-optical Bragg cell to be integrated in the laser cavity and the PulseSwitch control electronics. As an option APE offers a mounting-kit for holding the Bragg cell. The kit comes as a complete package for simple and fast installation into the laser system. The control electronic generates the RF carrier frequency for the Bragg cell based on a seed input signal with the repetition rate of the mode-locked system.
