The PulseSwitch for Coherent Mira is an intra-cavity acousto-optical switch for reducing the pulse repetition rate of mode-locked laser systems (cavity dumping). Inherently, this provides an increased output pulse energy. The PulseSwitch technology differs from the use of a pulse picker, which is placed external to the laser cavity, and only reduces the pulse repetition rate. The increased output pulse energy and peak power result in more efficient non-linear processes like SHG (Second Harmonic Generation) and THG (Third Harmonic Generation). The PulseSwitch has been developed for the Coherent Mira 900. For the application with other short pulse Ti:Sapphire laser systems please contact APE.
In a Coherent Mira 900, pulse energies of more than 50 nJ (at a repetition rate of 500 kHz, and a wavelength of 800 nm) are reached through cavity dumping. Obviously, this is several times the pulse energy typically reached with commercially available cw mode-locked Ti:Sapphire lasers.
Pulse repetition rates can be selected between 200 Hz and 9 MHz. An external trigger offers the possibility of even lower repetition rates, down to single shot. The spectral range of the system is tuneable from 700 ... 980 nm. A common application is the combination of the PulseSwitch cavity dumper with SHG. Therefore a version with an integrated SHG is available, reaching conversion efficiencies up to 40%.
As an option the PulseSwitch can also be operated as a pulse picker. Switching between the two operational modes is easy and fast. In the pulse picker mode, an optical bypass for normal operation is available.
In general, installation and de-installation of the PulseSwitch is simple and only minor changes on the laser are necessary.
