Three channel modulated laser source

This is a turnkey single-mode fiber coupled triple wavelength laser source designed for testing of photo- detector array.

Based on WT&T narrow spectra modules LD05SK and visible module LD04s, optical power output of each laser channel can be adjusted using control knob. Two IR lasers (900 to 1060 nm) can be modulated from external analog or digital generator. Visible laser is used for targeting.

Output power:   up to 50 mW each IR channel                        
Fiber output:     single mode fiber with FC/APC connectors
Long term wavelength drift:     < 150 pm
Modulation frequency:             up to 150 MHz
Modulation extinction ratio:     ~10 dB


Angled fiber with microlens

Shown here is an optical fiber (smf-28) having angle polished tip ~ 45 Deg with integrated focusing lens. This type of lens is found to be useful in optical sensing, instrumental and telecomm applicaitons.
