Tunable Laser <Lambda-Master>
Product Summary
Our wavelength tunable lasers use our proprietary transposed Littman-type
external resonator structure to completely separate the ASE from the output
optical axis without sacrificing optical output intensity, achieving both
high output intensity and high spectral purity (ASE-free). In addition,
the Littman configuration, which is a geometrically and mathematically
ideal configuration, is partially deformed to compensate for the dispersion
of the LD chip and optics to achieve mode hop-free tuning over a wide wavelength
bandwidth even in the 1um band, where chip dispersion becomes apparent,
let alone in the communication band. To fully use the performance of the
external cavity, a stepper motor type pressure contact slider with backlash-free
and ultra-precise motion is used as the wavelength tuning actuator to achieve
wavelength sweep performance that contributes to precision spectroscopic
measurement. Other features include an analog wavelength sweep function
using PZT, an auto-focus function for fiber couplings that takes advantage
of high output power, and a data acquisition function synchronized to wavelength
tuning, all of which can be fully utilized by the spectroscopic measurement
software to meet the high demands of laboratory users. The software is
available in executable file format, and LabVIEW source code is also distributed.
