The APE PulseSwitch is an acoustooptical switch for reducing the pulse repetition rate of modelocked laser systems while at the same increasing pulse energy. This is especially effective in combination with nonlinear processes like SHG and THG. In comparison to normal pulse pickers it is integrated into the laser resonator for intracavity operation. The APE PulseSwitch has been developed for the Coherent Mira 900F; for the application with other fs Ti:Sapphire laser systems please contact APE.

Our cavity dumper reaches pulse energies of more than 50nJ (@500kHz, 800nm), a multiple of the pulse energies usually reached with cw modelocked Ti:Sa lasers. Pulse repetition rates can be selected between 200 Hz to 9MHz. An external trigger offers the possibility of even lower repetition rates down to single shot. The spectral range of the system is tunable from 700 to 1000nm. For the range between 700 and 900nm a pump source of only 5W is necessary in order to achieve maximum pulse energy.

A number of customers would use a cavity dumper for the generation of SHG. Therefore a version with an integrated SHG reaching conversion efficiencies up to 40% is also available.

As an additional option for the ps operation of the Ti:Sa laser the PulseSwitch can also be operated as a pulse picker. Switching between the two operation modes is easy and doesn’t take much time.

In general, installation and deinstallation of the PulseSwitch are simple and only minor changes on the laser are necessary.
