Femtosecond Amplifier

Coherent Inc.Request Info

The Astrella HE femtosecond amplifier from Coherent Inc. delivers up to 9 mJ at a repetition rate of 1 kHz.

The Astrella HE integrates a titanium-sapphire oscillator, a single-stage regenerative amplifier, and a pulsed green 527-nm laser to pump the amplifier stage, all in a single box that measures 1247 × 755 × 262 mm. The use of closed-loop water cooling simplifies the installation of this titanium sapphire amplifier and lowers operating costs. The device has the same footprint, compact one-box format and user-friendly operating software as existing Astrella amplifier products. It is available with a choice of 35- or 100-fs pulse widths.

The amplifier can be used to pump multiple tunable optical parametric amplifiers to simultaneously run multiple experiments or single experiments that need multiple independently tunable wavelengths. It enables applications of extreme UV lithography, coherent radiation, or energetic electrons to industrial diagnostics, biology, material science, and microelectronics.
