Katana is a versatile, sub-nanosecond laser system designed for all industrial applications that require maintenance-free operation, continuous tuning of the repetition rate and low cost of ownership. It can provide pulses from 30 ps up to 10 ns in pulse duration. The Katana laser can be operated from pulse-on-demand up to 100 MHz, and it can also easily be triggered from an external source (master or slave mode). A single-box multi-wavelength version is available which, combined with the use of the Katana HP as a depletion laser, can provide a complete source for super-resolution fluorescence microscopy.
