SLD-53-HP: Very-high-power SLD modules at 1050 nm
Features:
Very high output power, up to 30 mW ex SM fiber
Up to 75 mW free space output on request
Flat spectrum with small residual Fabry-Perot modulation depth
Applications
- optical sensing
- optical coherence tomography
- optical measurements
Packages:
fiber coupled – Butterfly, DIL
free space – TOW
The following part numbers should be used when ordering:
SLD-53(a)-(b)-(c)-(d)-(e),
where: (a) – 0 (free space) or 1 (fiber pigtailed),
(b) – power category (HP1...HP3), (c) – package type,
(d) – SM (isotropic) or PM (polarization maintain) fiber (pigtailed versions only),
(e) – PD (if PD monitor is required).
Example: SLD-531-HP1-DBUT-SM-PD.
A maximum feedback of 10−3 is allowed to run HP SLDs safely at full
power.
All specifications are subject to change without notice.
