Unique rugged and compact design establishes PL2241 series picosecond lasers as versatile tool for research applications.

The heart of the system is diode pumped solid state (DPSS) master oscillator placed in hermetically sealed monolithic block. Combined, the DPSS master oscillator and flash lamp pumped regenerative amplifier offer reliable performance and hands free operation.

Up to 250 Hz repetition rate speeds up data acquisition and processing in spectroscopic systems.

Efficient power amplifier and harmonic generators

The optimized multiple-pass power amplifier with pulse polarization rotation between the passes efficiently extracts the energy stored in the rod, at the same time, maintaining near Gaussian beam profile and low wavefront distortion.

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.

Simple and convenient laser control

For customer convenience the laser is controlled through its RS 232 type PC interface with LabView drivers (included) or a user-friendly remote control pad. 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.

Build in energy monitors ensure easy operation control. Data from the energy monitor can be seen on the remote keypad or PC monitor via the LabView drivers. LabView drivers, supplied together with the laser, enables long term monitoring of the output energy.

Software can protect optics from the accidental increases of pulse energy, by providing user with alerting messages and by stopping the laser, when the pulse energy exceeds the preset level.
