This is single longitudinal frequency CW laser which is tunable in range between 1027 nm and 1033nm (6nm). Continuous wavelength tunable is possible with mode-hop free condition by modulating temperature on DFB (distributed – freedback) laser diode between 0°C〜80°C.
Narrow line-width laser can be obtained with low noise.
Size is compact because of no using external grating and wavelength variable filter.
