The PT400 Series from EKSPLA are Tunable Wavelength Picosecond Lasers that operates from 210 to 2300 nm. They provide an output pulse energy from 10-70 µJ with a pulse repetition rate of 1000 Hz and have a pulse duration of 15 ps. These lasers are dual-polarized and have a power consumption of less than 120 W. They have an integrated pump laser which is based on EKSPLA’s PL2210 series picosecond mode-locked laser and an optical parametric generator which is based on the PGX03 picosecond optical parametric amplifier systems. These lasers can be controlled via USB and RS-232 interfaces and offer better long term stability with low maintenance costs. They are ideal for time-resolved fluorescence, pump-probe spectroscopy, laser-induced fluorescence, infrared spectroscopy, nonlinear spectroscopy such as surface-SH, Z-scan, and nonlinear optics applications.
