8-10mw 1653.5nm Butterfly Laser Diode for Gas Detection

0.0/5 rating (0 votes)

Description

The 8-10mw 1653.5nm Butterfly Laser Diode for gas detection (ultra narrow linewidth 1653nm butterfly laser diode) are provided in a 14-pin butterfly package.The equipment adopts the high-quality InGaAsP/InP strained MQW-DFB laser chip and is outfitted with a built-in cooler to prevent the equipment from overheating.It delivers single-mode optic fiber output and high-speed modulation at a maximum output power of 10MW.This series of laser equipment is designed based on external-cavity lasers with a built-in fiber Bragg grating which ensures a stabilized wavelength output,ultra-narrow spectral linewidth,and outstanding side-mode suppression ratio.It is commonly used in many scientific research fields as the optical gas detector,optical chemical sensor,optical testing equipment,fiber performance testing equipment,and the light source of OTDR systems.

 

Features
¡ô The Butterfly Laser Diode are capable of producing laser light at a stabilized wavelength.
¡ô Typical values for the equipment are up to 1653.3nm for the peak wavelength, spectral linewidth up to 100 KHz, minimum output power 8MW, and minimum SMSR 35dB.
¡ô The equipment is supplied with a thermoelectric cooler and thermistor.
