888nm Fiber Coupled Laser

888nm Fiber Coupled Laser product image

Overview

The 888nm Fiber Coupled Laser series covers 30–270 W of wavelength-locked output for Nd:YVO₄ in-band pumping. At 888 nm the crystal absorbs almost independently of polarisation, which spreads the pump deposition more evenly along the rod than 808 nm pumping does.

  • Power & fiber — 30–270 W across six models; 200 µm core / 220 µm cladding, fiber NA 0.22, SMA905 output, 1.5 m lead
  • Spectrum — 887.3–888.7 nm centre, 1 nm FWHM, 0.02 nm/°C temperature drift
  • Wavelength locking — locked from 30% to 100% of rated power
  • Drive & protection — 13–14 A at 5–42 V depending on power, 47–50% electro-optical efficiency, 1030–1200 nm return-light isolation
  • Cooling — conduction cooled; 20–25 °C coolant temperature required

Notes

  • Photoelectric data are referenced to the test conditions stated in each source specification; most source sheets use 25°C.
  • Output power, fiber specifications, connector type, and fiber length can be customized where indicated.
  • Use appropriate electrostatic-discharge protection during transport, storage, and operation.
  • Clean the fiber end face before use and avoid contamination or damage.
  • Operate the laser with a constant-current supply and within the rated current, voltage, and power limits.
  • Provide effective cooling; the source sheets generally recommend a cooling-water temperature of 23-25°C.
  • Avoid direct eye or skin exposure to laser radiation and follow wavelength-appropriate laser-safety procedures.
  • Do not bend the fiber sharply; follow the minimum bend-radius guidance in the applicable source specification.
