Product Introduction

STKM-YFi High Power and Repetition Rate Near-IR Ultrafast Fiber Lasers

The STKM-YFi laser series is a family of high average power, high repetition rate near-IR ultrafast fiber lasers. STKM-YFi products are based on a single rugged opto-mechanical platform and are engineered for hands-free operation.

STKM-YFi Outstanding Characteristics

The STKM-YFi system employs a patented all normal dispersion (ANDi) mode-locked fiber laser coupled with a fiber amplifier. This configuration offers numerous unique advantages, including:

The short, clean pulses of the STKM-YFi laser series deliver more peak intensity per mJ than competing products. We guarantees both pulse duration and pedestal energy content, verified with a FROG pulse measurement, to ensure each laser pulse is free of picosecond background that robs energy from the main short pulse. Thus, more of the laser output is truly usable, requiring less energy/average power and decreasing the probability of seeing collateral damage and other detrimental interactions.

STKM-YFi OPA Robust, Briefcase-sized Tuneable Ultrafast SWIR/MWIR Source

The STKM-YFi OPA is our vertically integrated optical parametric amplifier pumped by a STKM-YFi HP. The class-leading pulse duration of the 1035 nm centred STKM-YFi HP results in both a stable, coherent white light seed source and exceptionally high conversion efficiency into the short-wave and mid-wave infrared.
