Pulsed fiber lasers utilize a doped fiber optic cable as the gain medium, rather than the crystals utilized in DPSS lasers, and provide pulsed output, as opposed to CW lasers, which emit a continuous output beam.
Typically, the fiber laser’s gain medium is doped with a rare-earth element, such as erbium (Er), ytterbium (Yb), or neodymium (Nd), just like the crystals used in most DPSS laser systems. However, fiber lasers offer several advantages over traditional DPSS lasers (e.g., Nd:YAG lasers). Some of these advantages derive from the geometry of the fiber optic itself, namely, the innate ability to have an extremely long single-mode optical cavity. This geometry produces either extremely high-power single-mode fiber lasers exhibiting unprecedented brightness or extremely narrow band lasers with near-perfectly single-frequency output.
Another advantage is that the fiber medium is flexible, which makes it easier to deliver the beam exactly where you need it. This ability can be highly advantageous when dealing with complex geometries and tight spaces. Typically, fibers exhibit a complex temperature-dependent polarization evolution, except for example, if utilizing polarization-maintaining fibers or Faraday rotators. However, these solutions are typically not compatible with nonlinear polarization rotation mode locking.
Since the fiber optic acts as a gain medium, several kilometers long in some cases, high-power fiber lasers benefit from the high optical gain and can provide much higher output powers compared to some other laser types. The extremely high surface area to volume ratio provides the inherent ability to efficiently remove heat generated, allowing continuous output of kilowatt levels of output power. The waveguide properties of the optical fiber mitigate thermal distortion, producing high-quality, near-diffraction-limited or better optical beam output (i.e., better beam quality). It should be noted that fiber lasers are different than fiber-coupled lasers. Fiber-coupled lasers simply have the beam output coupled into a fiber, as opposed to free-space output, and do not share all the same benefits as detailed above. However, fiber lasers do rely on one or more fiber-coupled laser diodes to pump the gain medium. Fiber amplifiers, lacking the ‘cavity’ to enable lasing, also rely on fiber-coupled diode pumps.
