Calmar Laser has released a 780-nm OEM or desktop femtosecond fiber laser for terahertz radiation imaging, optical metrology and multiphoton microscopy applications. The instrument delivers pulse energy up to 1 nJ, peak power up to 10 kW and average power >50 mW at 50 MHz. With selectable wavelengths from 765 to 780 nm, it produces pulse widths <0.1 ps with minimal pulse pedestal and near-transform-limited output. It offers linearly polarized output, low timing jitter, radio-frequency synchronization output and turnkey operation. It requires no external cooling. The laser also is suitable for biophotonics, optical metrology, terahertz radiation imaging and materials characterization applications, and for seeding Ti:sapphire amplifiers.
