Coherent has released the Pavos kW Ultra, an optical isolator designed to withstand up to 1kW of power, for applications involving high-energy ultrashort-pulse (USP) lasers.

The isolator is ideal, the firm says, for USP lasers operating at one-micron wavelengths such as fibre lasers and diode-pumped solid-state lasers. It allows femtosecond-pulse lasers to maintain beam quality at a high pulse energy, making it suitable for cutting and marking carbon-fibre-reinforced polymer (CFRP) in automotive and aerospace applications. 

According to Coherent, Pavos kW Ultra offers high isolation and beam quality while achieving about one-tenth the absorption and thermal lens focal shift compared with existing products. The isolator features a 12 mm aperture that enables large laser beam size, significantly increasing the laser damage threshold.

“We are bringing to the market a unique solution that has already been validated with live femtosecond laser trials in customer labs,” said Dr Chris Koeppen, Chief Innovation Officer at Coherent. “This product integrates our breakthrough innovations in magneto-optic crystals, thin-film coatings, and polariser optics, resulting in a vertically integrated product with highly differentiated performance.”

The Pavos kW Ultra will be generally available by autumn.
