Ekspla Multiple Channel APL series picosecond amplifiers were designed and manufactured for multiple stage OPCPA pumping. Systems can be specially tailored for customer‘s needs and have up to 8 pumping channels with different wavelength, energy, pulse duration, spatial and temporal profiles, adjustable delay, image translation to customers specified location and various other features.
Short pulse duration, excellent pulse‑to-pulse stability, superior beam quality makes APL series picosecond amplifiers well suited for other applications as well.
REGENERATIVE AMPLIFIER / POWER AMPLIFIER DESIGN
APL 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.
Alternatively Ekspla can offer an internal seeder meeting customer’s requirements.
FULL-FIBER FRONT-END
Novel Ekspla developed fiber front‑end opens up new set of unique features for APL systems like dual wave seeder that also has burst formation functionality due to active fiber loop technology. The front‑end also permits to offer powerful, ultrafast and higher frequency Ytterbium amplifiers for wider opportunities in OPCPA pumping and other scientific uses.
