“1mm Band ASE-Free Tunable Diode Laser”
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.
