APL210x series amplifiers are designed to produce up to 2200 mJ picosecond pulses. High pulse energy, excellent pulse-to-pulse energy stability, superior beam quality makes APL210x series picosecond amplifiers well suited for applications like OPCPA pumping, non-linear optics and others. Ekspla can offer a seeder meeting customer’s requirements.

Regenerative amplifier / Power amplifier design

APL210x series amplifiers are designed to be seeded by external seeding source. Diode pumped regenerative amplifier ensures amplification of seed signal to stable mJ level pulse for amplification in linear amplifiers. Advanced beam shaping ensures smooth, without hot spots beam spatial profile at the laser output. Low light depolarization level allows high efficiency generation of up to 4th harmonic with optional build-in harmonic generators.

Build-in harmonic generators

Angle-tuned DKDP crystals harmonic generators mounted in temperature stabilized heaters are used for second, third and fourth harmonic generation. Harmonic separation system is designed to ensure high spectral purity of radiation and direct it to the output ports.

Simple and convenient laser control

For customer convenience the amplifier can be controlled through remote control pad or USB interface. The control pad features a backlit display that is easy to read even while wearing laser safety eyewear. Alternatively, the amplifier can be controlled from personal computer with supplied software for Windows™ operating system. LabVIEW™ drivers are supplied as well.

  1. Due to continuous improvement, all specifications are subject to change. Parameters marked typical are illustrative; they are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise, all specifications are measured at 1064 nm and for basic system without options.
  2. For APL210x-SH and APL210x-SH/FH options. Outputs are not simultaneous.
  3. For APL210x-TH option. Outputs are not simultaneous.
  4. For APL210x-SH/FH option. Outputs are not simultaneous.
  5. Averaged from pulses, emitted during 30 sec time interval.
  6. Optional 30 ps duration. Inquire for pulse energies.
  7. Should be specified when ordering. Inquire for custom pulse repetition rates.
  8. Gaussian fit >80%.
  9. Full angle measured at the 1/e² level at 1064 nm.
  10. Beam diameter is measured at 1064 nm at the 1/e² level.
  11. Value measured from 300 shots.
  12. Required current rating can be calculated by dividing power rating by mains voltage.

Note: Laser must be connected to the mains electricity all the time. If there will be no mains electricity for longer that 1 hour then laser (system) needs warm up for a few hours before switching on.
