The LBTEK Tunable Diode Laser offers continuously tunable output wavelength within a defined range, with six selectable wavelength bands covering the visible to near-infrared spectrum. The laser’s controller features a touchscreen interface, allowing users to set the drive current, piezoelectric actuator voltage, and internal temperature with precision.
Each unit is supplied with 0.9 mm and 2.0 mm hex keys for wavelength tuning adjustments. The laser is characterized by its high stability, low noise, and narrow linewidth (< 0.1 nm). Tuning resolution reaches the picometer level, with a minimum wavelength tuning step of approximately 1 pm.
