neoMOS-70ps Picosecond MOPA Laser
The neoMOS picosecond laser series combines the reliability and low maintenance of a state of the art picosecond laser diode with a solid-state amplifier. Customized combinations with different output powers and flexible repetition rates are integrated into a ultra-compact laser head enabling easy system integration. High stability and long lifetime are provided by design for 24/7 industrial use.

The increasing demands in laser material applications require high flexible and comprehensive laser systems. For these areas neoLASE developed a new picosecond laser system with a unique flexibility in terms of pulse control. With the flex pulse technology the lasers repetition rate and the pulse energy can be changed continuously. The system is based on a laser diode emitting 70 ps long laser pulses which can be triggered for each pulse individually. The pulses sequence therefore can be arbitrary and set from single pulses up to 50 MHz repetition rates or can be synchronized with scanners or moving axes. The use of a frequency sweep for example can produce gray scale pictures without changing the scanners speed. A second control input enables free pulse energy control up to 250 µJ which can be correlated to changes in the repetition rate or adapted to different processing steps. The full flexibility of the system is illustrated in Fig.2 showing that the pulse sequence and energy can be adapted to the application.
