仪器简介：
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.
