Pulse-Width-Tunable Semiconductor Light Source Tuna

Pulse-Width-Tunable Semiconductor Light Source Tuna

The Tuna series features pulse-width-tunable semiconductor light sources with adjustable pulse width, high output power, and flexible user-defined output parameters. It is suitable for detector response time, excited-state lifetime, and transient photoconductivity measurements, and is widely used in the study of phosphors, dyes, organic semiconductors, perovskites, and quantum dots.

Description

Pina, NanoQ, Mic, and Tuna are next-generation compact semiconductor light sources from Oriental Spectra for advanced optical applications. Each series includes two variants based on semiconductor laser and UVLED technologies. These sources cover a broad spectral range from UV–Vis–NIR in the frequency domain and support picosecond, nanosecond, microsecond, and pulse-width-tunable operating modes. All models feature synchronized trigger output and flexible external trigger input. They can be used as standalone laser modules for custom free-space optical setups or coupled with spectrometers and fiber optic systems. The Tuna series, with its adjustable pulse width, high output power, and customizable parameters, is designed for detector response time, excited-state lifetime, and transient photoconductivity measurements, and is commonly applied in research on phosphors, dyes, organic semiconductors, perovskites, and quantum dots.
