Description
The DC‑250/50‑PM‑Tm is a high‑performance flexible double‑clad polarization‑maintaining photonic crystal gain fiber manufactured by NKT Photonics, specially doped with thulium (Tm) rare‑earth ions, optimized for 1930‑2000 nm 2‑micrometer band fiber laser and fiber amplifier systems. This fiber is officially classified as dual‑use controlled item, relevant international and national export‑control regulations shall be complied with for any cross‑border transaction.
Adopting advanced air‑clad photonic crystal fiber architecture, this gain fiber features 250 μm pump cladding diameter and 50 μm signal core structure, delivers large mode‑field diameter around 38 μm at operating wavelength, effectively suppresses harmful nonlinear optical effects while supporting high average power and high pulse‑energy output, and guarantees excellent single‑mode beam quality (low M² factor). Built‑in polarization‑maintaining design preserves stable linear polarization status during operation, which is critical for laser systems requiring consistent polarization state. High‑NA pump cladding enables efficient multi‑mode pump light absorption under 793 nm pumping source, reducing required fiber length and system volume for laser‑oscillator or amplifier setupNKT Photon….
With flexible mechanical property, the fiber supports reasonable bending radius installation, adapts to compact OEM laser cabinet integration. High‑temperature resistant acrylate coating enhances thermal‑stress resistance, improves reliability under long‑time high‑power running conditions, lowers risk of thermal damage for gain fiber inside laser devices.
Typical application scenarios include 2 μm continuous‑wave & pulsed thulium fiber lasers, medical surgical laser equipment for urology, ENT and soft‑tissue ablation, scientific research laser amplifiers, industrial material processing, as well as photonic‑experiment platforms. Due to dual‑use‑item attribute, end‑user usage, end‑user statement and export‑license documentation are mandatory for international trade. Buyers shall undertake full responsibility to observe local export‑control laws and regulatory requirements.
It serves as core gain medium for OEM laser integrators, research institutes and photonics laboratories. When paired with qualified 793 nm pump diodes, it achieves high‑slope‑efficiency laser output within 1.9‑2.2 μm spectral range.
