CLPF-2400 Cr:ZnSe/S ultrafast oscillators provide 20-150 fs pulses in the range of 2.1-2.6 μm at 80-1000 MHz pulse repetition rate. Both fixed frequency and tunable models are available. The Kerr-lens mode-locked optical head is pumped by IPG’s efficient and reliable CW erbium fiber laser. CLPF Series models with extended output power, wavelength range, automated wavelength tuning, and synchronization to an external clock or another oscillator are offered as an option. Other options, such as CEP stabilization option are coming soon. CLPF lasers address a wide range of scientific and biomedical applications. Please discuss your needs with an IPG Photonics' representative.
