The PL2230 Series from EKSPLA are Diode Pumped Picosecond Nd:YAG Lasers that operate at 213, 266, 355, 532, and 1064 nm. They deliver an output pulse energy of up to 5 mJ at 213 nm and up to 40 mJ at 1064 nm. These lasers have a repetition rate from 0-100 Hz and a pulse duration (FWHM) of up to 28 ps. They have a beam diameter of 5 mm, beam divergence of under 1.5 mrad, and beam pointing stability of less than 20 µrad.
The PL2230 Series have a hermetically sealed DPSS master oscillator which produces high repetition rate pulse trains of 88 MHz with low single pulse energy. They consist of a high-gain regenerative amplifier which has an amplification factor in the proximity of 106. The pulse obtained from the regenerative amplifier is directed to a multipass power amplifier that is optimized for efficient stored energy extraction from the Nd: YAG rod while maintaining a nearly Gaussian beam profile and low wavefront distortion. They also feature angle-tuned KD*P and KDP crystals which are mounted in thermostability ovens and are used for second, third, and fourth harmonic generation. Harmonic separators ensure the high spectral purity of each harmonic guided to different output ports. The energy monitors continuously monitor output pulse energy and the data from the energy monitor can be seen on the remote keypad or a PC monitor.
The PL2230 Series require an AC supply voltage from 110-240 V and consumes up to 1.0 kVA of power. They are available as a bench-top unit with a laser head that measures 471 x 391 x 147 mm. These lasers are ideal for use in time-resolved spectroscopy, SFG/SHG spectroscopy, nonlinear spectroscopy, OPG pumping, remote laser sensing, satellite ranging, and other spectroscopic and nonlinear optics applications.
