Ekspla is proud to introduce the first commercial fully diode-pumped high pulse energy mode-locked laser producing 28 ps pulses with up to 35 mJ (preliminary version with 50 mJ) at 50 Hz pulse repetition rate.

Innovative design

The heart of the system is a diode-pumped solid-state (DPSS) master oscillator placed in a sealed monolithic block. At a high repetition rate, it produces pulse trains (88 MHz) with a low single pulse energy of several nanojoule. Diode-pumped amplifiers are used for amplification of the pulse to 35 mJ (140 mJ preliminary) output. The high‑gain regenerative amplifier has an amplification factor in the proximity of 106. After the regenerative amplifier, the pulse is directed to a multipass power amplifier. It is optimised for efficient extraction of stored energy from the Nd:YAG rod while maintaining a near Gaussian beam profile and low a wavefront distortion. The output pulse energy can be adjusted in approximately 1 % steps while pulse‑to-pulse energy stability remains at less than 0.5 % rms at 1064 nm.

Angle-tuned KD*P and KDP crystals mounted in thermostabilised ovens are used for second, third and fourth harmonics generation. Harmonics separators ensure the high spectral purity of each harmonic guided to different output ports. Built-in energy monitors continuously monitor output pulse energy. The data from the energy monitor can be seen on the remote keypad or on a PC monitor. The laser provides triggering pulses for the synchronisation of your equipment. The lead of the triggering pulse can be up to 500 ns and is user-adjustable in ~0.25 ns steps from a personal computer. If required, up to 1000 μs lead of triggering pulse is available by installing a PRETRIG option. Precise pulse energy control, excellent short-term and long-term stability and a 50 Hz repetition rate makes the PL2230 series lasers an excellent choice for many demanding scientific applications.

Simple and convenient laser control

For customer convenience, the laser can be controlled through a user‑friendly remote control pad or USB interface. The remote pad allows easy control of all parameters and features a back‑lit display that is easy to read even with laser safety eye-wear. Alternatively, the laser can be controlled from a personal computer with supplied software for Windows™ operating systems. LabView™ drivers are supplied as well.
