The Pulse Switch for Mira-900 ultrafast oscillators is a compact, bolt-on accessory enabling cavity-dumped operation to produce higher pulse energy at lower repetition-rates.
With Pulse Switch, the Mira cavity is extended to include the Pulse Switch’s acousto-optic modulator. By using intracavity acousto-optic modulation to switch pulses out of the Mira cavity, Pulse Switch provides a convenient way both to reduce laser repetition rate and increase output pulse energy. Providing repetition rates variable from 9 MHz down to single shot, and pulse energies up to 60 nJ, Pulse Switch is ideal for processes and experiments that benefit from lower duty cycle and/or higher pump intensity.
Pulse Switch is compatible with the Mira 900-F and 900-D (femtosecond cavity). The capabilities of the Pulse Switch may be further extended with an optional integrated frequency doubling module, which provides conversion efficiencies typically up to ~40%.
