750-800nm SLD高功率宽带模块

我们的主要产品是波长从650nm到1620nm具有不同谱带的单模尾纤SLD模块。

我们正在为不同的应用制造制冷(有制冷器和电热调节器)和非制冷的模块，像光纤陀螺仪、OCT、光纤组件测试、光计量学和大量的其它模块。我们也提供自由空间模块，特别是用于原子力显微术，但也包括无斑纹照明、白光干涉测量、光学试验和测量以及其它模块。

Model number：SLD-33-HP

特征：

- 3 power categories: an output power of up to 25mW ex SM fiber

and a spectral width (FWHM) of 50 nm

- short coherence length

- negligible residual Fabry-Perot modulation depth

 

封装：

- fiber coupled – Butterfly, DIL

- free space – TOW

 

应用：

- fiberoptic sensors

- Bragg grating sensors

- optical coherence tomography

- optical measurements

 

Additional & customized:

- PD monitors

- FC/APC terminated pigtails

- PM pigtails (polarized or depolarized output emission ex PM fiber)

* TOW packaged SLDs;

† current is specially adjusted to get highest output power with equal intensity of

spectral lobes; different for different modules;

‡ Spectral Flatness parameter describes spectral intensity dropout between

spectral lobes;

** Pseudo-depolarized versions (light is launched into the fiber with its

polarization oriented at 45° to the birefringent axes) are available upon request;

†† Butterfly packaged SLDs.

 

Note: SLD spectra for the batches in stock are available upon request.

 

The following part numbers should be used when ordering:

SLD-33(a)-(b)-(c)-(d)-(e),

where: a – 0 (free space) or 1 (fiber pigtailed);

b – power category HP1, HP2 or HP3; c – package type;

d – SM or PM (fiber coupled modules); e – PD (if PD monitor is required).

Example: SLD-331-HP1-DIL-SM-PD.

 

A maximum feedback of 10−3 is allowed to run HP SLDs safely at full

power.
