Request InfoCoherent Inc.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...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2023 IssueLaser Cutting HeadsThe BIMO-FSC3 line of laser cutting heads from Coherent Corp. features high-power ratings for materials processing.
