IPG PYL-2 1360nm Laser

The PYL-R and PYL-R2 Series Raman Lasers consist of two components – a Ytterbium fiber laser and a Raman wavelength shifter. The Ytterbium laser is a telecom-grade version of the IPG PYL series single-mode fiber laser operating at wavelengths between 1050 nm and 1120 nm. The Raman shifter employs two advanced technologies in a cascaded Raman resonator cavity: Bragg fiber gratings and WDM couplers. The resonator efficiently converts the input pump laser wavelength to the chosen output wavelength. The output is single mode and randomly polarized. Typically there is a > 30 dB fiber isolator at the output. All PYL-R Series Raman Lasers incorporate broad stripe 1x100 µm pump diodes operating at a 970 nm nominal wavelength to pump the Ytterbium laser pump. Pump diode reliability corresponds to a MTTF of 5,000,000 hours at the nominal operating current and a temperature of 20°C. All pump diodes are subjected to intensive component qualification at IPG Photonics prior to installation.
