Where to Buy Mode-locked Lasers

The MLL-100 generates sub-100 fs laser pulses at 100 and 200 MHz. Control inputs for cavity length and oscillator pump power allow control over f_opt and f_CEO, respectively.

The Stuttgart Instruments Primus is an ultrafast (fs) mode-locked oscillator, based on the solid-state technology. It provides a high average output power combined with a superior low noise level (shot noise limit above 300 kHz) and an excellent long-term stability.

The solid-state technology with 1040 nm central wavelength enables the excellent long-term stability by providing several watts of output power at 40 MHz pulse repetition rate and 450 fs pulse duration. Its superior low noise level reaches the shot noise limit above 300 kHz. In combination with the stability and output power, it enables ultrasensitive measurements and makes the Primus perfectly suited as pump source for frequency converters like the Stuttgart Instruments Alpha. The entire system is encapsulated in a solid CNC-cut and water-cooled housing, thus reaching excellent robustness against external perturbations.
