The smallest but not the least, the PErL is an ultrafast fiber laser operating in C-band (1530-1565 nm). The rigid design of the laser ensures insensitivity to physical and vibration impact, high stability, repeatability of initial specs that is in high demand with OEM applications. There are two versions of the laser: the PErL-OEM being a cost-effective minimalistic version without linearly polarized output, and the PErL-PM version with linearly polarized output and ultra-short pulse capability.

For the PErL-OEM, the pulse duration can be ordered in the range of 250 fs...5 ps, pulse shape being close to transform-limited. The PErL laser with average power rating up to 50 mW is a nice budget-friendly solution for low-power ultrafast applications.The only thing needed for OEM operation is a power source with +5 V (the power adapter for standard 110/220 V network is supplied with the laser).

The PErL-PM features PM fiber architecture and PM fiber socket output with fiber pigtail lengths up to 1 m. An optional free-space collimator may also be supplied with the unit. The system offers pulse duration as low as 50 fs and is a versatile tool for semiconductor studies and for THz generation.

High frequency electrical outputs of either version can be used as a trigger source for synchronization systems. The laser can act as a stand-alone pulse source, as well as operate in complex systems.

- output collimator upon request;
- PErL-PM-SH version with built in SHG (780±5 nm, >30 mW, <120 fs)
- OEM customized versions for integration into customer's equipment.

Q: What is the output polarization of this laser?
A: Output polarization for this system is not specified and has random nature. Linear polarization is possible upon request.
