PL2250 series picosecond mode-locked Nd:YAG lasers sets new standard in high pulse energy picosecond lasers. Innovative and cost effective design allows to improve laser reliability, while reducing running and maintenance costs.
INNOVATIVE DESIGN
The heart of the system is diode pumped solid state (DPSS) master oscillator placed in hermetically sealed monolithic block. The flashlamp pumped regenerative amplifier is replaced by innovative diode pumped regenerative amplifier. Diode pumping results in negligible thermal lensing, which allows to operate regenerative amplifier at variable repetition rates, improved long-term stability and maintenance-free operation.
The optimized multiple-pass power amplifier is flashlamp pumped and is optimized for efficient amplification of the pulses while maintaining near Gaussian beam profile and low wavefront distortion. The output pulse energy can be adjusted in approximately 1 % steps from 1 mJ to nominal output, at the same time pulse-to-pulse energy stability remains less than 1.5 % rms @1064 nm.
Angle-tuned KD*P and KDP crystals mounted in thermostabilised ovens are used for second, third and fourth harmonic generation. Harmonics separators ensure high spectral purity of each harmonic directed to different output port.
Build in energy monitors continuously monitors output pulse energy. Data from the energy monitor can be seen on the remote keypad or on PC monitor. The laser provides triggering pulse for synchronization of customer‘s equipment. The lead or delay of triggering pulse can be adjusted in ~45 ns steps from control pad or PC. Up to 500 μs lead time of triggering pulse is available as option.
Precise pulse energy control, excellent short-term and long-term stability, up to 50 Hz repetition rate makes PL2250 series lasers excellent choice for many demanding scientific applications.
SIMPLE AND CONVENIENT LASER CONTROL
For customer convenience the laser can be controlled through user-friendly remote control pad or USB interface.
The remote pad allows easy control of all the parameters and features a backlit display that is easy to read even while wearing laser safety eyewear.
Alternatively, the laser can be controlled from personal computer with supplied software for Windows™ operating system. LabView™ drivers are supplied as well.
