…low as 25 fs to the picosecond regime, and a broad range of energies per pulse. Configurable between 1 and 10 kHz and designed for water, TEC or cryogenic cooling depending on the average power level, Legend Elite HE+ offers ultimate performance for sophisticated experiments like attosecond physics,…

…Evolution pump laser.
Legend Elite
Duo HE+
Legend Elite DUO HE+ models achieve power levels previously
available only through cryogenic cooling. A single-pass amplifier
(SPA) stage is added between the regen and compressor, and the two
Titanium:Sapphire crystals are…

…enough to withstand the harsh conditions of space. "Beryllium was chosen because it is extremely light and stiff, with low thermal expansion at the cryogenic temperatures at which the observatory will operate," Turk said. "However, beryllium is a challenging material to polish, and requires special…

had been largely restricted to laboratory
applications because of the need to refresh
the gas mixture and the requirement for
cryogenic cooling.
Applications scientists at Art Photonics
in Berlin have been following up on earlier studies with experimental CO lasers

…cost effective enough for commercial use. In particular, early CO lasers
required cooling in order to reach high
output power, e.g. cryogenic cooling for
very high powers. Also, while the first
sealed CO
2
lasers could operate at high
powers for hundreds of hours,…

CEP for Legend Elite Amplifiers

CEP for Legend Elite Amplifiers

…Legend Elite Duo CEP delivers up to 10 Watts of power, as well as higher repetition rates (up to 10 kHz), yet it does not require the complexity of cryogenic cooling of the gain medium, unlike systems offered by competitors. With the Verdi pumped Vitara CEP and the Evolution pumped Legend Elite CEP,…

…crystal is cooled in
some way. This can take the form of a passive heat sink, water cooling, thermoelectric (TE)
cooling and even cryogenic cooling. Irrespective of the type of cooling, heat removal takes place
through one or more of the crystal surfaces. Under steady state operation,…

for is its Ti:sapphire lasers, many of them aimed at science. For
example, its Wyvern regenerative Ti:sapphire amplifiers have
cryogenic cooling to 50 K, which the company says eliminates
thermal lensing and boosts the power-handling capacity by up
to two orders of…

…involving very limited
lifetime and reliability caused by difficulties
in cooling the laser. In fact, the first CO lasers
required cryogenic cooling, which kept them
from being used in any commercial applications. Coherent recently developed new technology that has enabled the…
