Product Introduction

2000nm—3500nm Mid‐IR DFB Lasers

NORCADA designs and manufactures single mode semiconductor distributed feedback (DFB) lasers for industrial sensing and environmental monitoring applications.  Our DFB lasers come with two main styles of hermetic packaging configurations designed for excellent temperature stability andwavelength tuning.

 

Typical wavelengths for trace gas sensing applications

Gas气体CO2NH3N2OCOCO/CH4HFH2OCH4
λ(nm)波长(nm)20042239226023262334247524703270

 

Features

- Integrated DFB grang provides single frequency operaon

- Frequency tuning can be accomplished by adjusng either laser drive current or temperature.

- Tuning range up to 6 nm without mode hopping

- Temperature tuning control:  0.1 nm / °C

- Drive current tuning control:  0.04 nm / mA 

- Output Power:  10‐20 mW 

- Narrow linewidth <2 MHz
