Overview
The LTB ATM Series Automated Tunable Dye Laser is a modular, compact, and industrially engineered pulsed laser system designed for high-reproducibility spectroscopic applications requiring broad spectral coverage across the deep ultraviolet (DUV), visible (VIS), and near-infrared (NIR) ranges. Based on optically pumped dye gain media, the ATM leverages stimulated emission in organic dye solutions to generate tunable nanosecond pulses. Its core architecture follows the standard transverse-pumped, longitudinal cavity design optimized for use with nitrogen lasers (337 nm), excimer lasers (308 nm, 351 nm), or frequency-doubled Nd:YAG sources (266 nm, 355 nm). When integrated with the LTB MNL-series industrial-grade molecular nitrogen lasers—specifically the MNL 100HP—the ATM achieves full automated tuning from 225 nm to 950 nm, enabled by interchangeable dye cells and an integrated second-harmonic generation (SHG) module. The system delivers kW-level peak power pulses with typical pulse widths of ~3 ns (FWHM), repetition rates up to 30–50 Hz depending on configuration, and beam parameters suitable for fiber coupling and integration into OEM instrumentation platforms.
Key Features
- Automated wavelength selection and cavity alignment via Windows-based control software with intuitive GUI
- Modular design supporting multiple pump sources: 337 nm (MNL series), 308/351 nm (excimer), 266/355 nm (Nd:YAG harmonics)
- Three standardized configurations: ATM100 (broadband, 5–8 nm bandwidth), ATM200 (narrowband, ≤2 nm, continuously tunable via Littrow grating), and ATM-UV1 (full DUV–NIR coverage including SHG)
- Single-output port supporting direct free-space output or multimode quartz fiber coupling (core diameter compatible with standard 600 µm fibers)
- Integrated energy monitoring sensor and SHG phase-matching optimization feedback loop
- DLL-based API for seamless integration into custom automation frameworks, complying with industrial control standards
- No dye recirculation or cell cleaning required during operation; 15 pre-characterized, plug-and-play dye cells cover full 225–950 nm range
Sample Compatibility & Compliance
The ATM series is engineered for laboratory and industrial environments demanding long-term stability and traceable performance. All optical components meet ISO 10110 surface quality specifications, and mechanical assemblies conform to DIN EN 61326-1 (EMC for laboratory equipment). While not classified as a medical device, its output characteristics align with requirements for analytical instrumentation referenced in ASTM E275 (UV-Vis spectrophotometry), ISO/IEC 17025 (testing laboratory competence), and USP (laser-based analytical methods). For regulated environments (e.g., pharmaceutical QC labs), the system supports audit-trail-capable logging when paired with compliant host software adhering to FDA 21 CFR Part 11 principles (electronic records and signatures).
Software & Data Management
Control is executed through LTB’s proprietary Windows application, offering synchronized management of pump laser timing, dye cell selection, grating angle positioning (ATM200), SHG crystal orientation, and real-time pulse energy readout. The software provides programmable scan sequences—including step-scan, continuous sweep, and user-defined wavelength lists—with timestamped metadata export in CSV and XML formats. An optional SDK includes C/C++ and LabVIEW-compatible DLLs enabling integration with third-party DAQ systems (e.g., National Instruments PXI), spectrographs (Andor, Princeton Instruments), or time-correlated single-photon counting (TCSPC) platforms. All configuration files are stored in human-readable JSON format, facilitating version control and GLP/GMP-compliant documentation workflows.
Applications
- Laser-Induced Fluorescence (LIF) spectroscopy for combustion diagnostics and plasma characterization
- Time-Resolved Fluorescence (TRF) and fluorescence lifetime imaging (FLIM) in biomedical research
- Ultrafast pump-probe experiments requiring precise, tunable excitation in the DUV–NIR range
- Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) source development
- OEM integration into portable Raman spectrometers, cavity ring-down absorption systems, and photoacoustic gas analyzers
- Calibration of monochromators, spectroradiometers, and photodetector quantum efficiency setups per CIE and NIST traceable protocols
FAQ
What pump lasers are compatible with the ATM series?
The ATM is optimized for 337 nm nitrogen lasers (e.g., LTB MNL 100HP), but can be customized for 308 nm/351 nm excimers or 266 nm/355 nm Nd:YAG harmonics upon request.
Is continuous tuning available across the entire 225–950 nm range?
No—tuning is discrete per dye cell. Full coverage requires 15 pre-aligned cells; continuous tuning is limited to 400–950 nm (ATM200) or 225–400 nm (ATM-UV1 SHG mode).
Can the ATM be integrated into a vacuum chamber environment?
Yes, with optional vacuum-rated feedthroughs and non-outgassing optical mounts; contact technical support for chamber interface specifications.
Does the system support external triggering and synchronization?
Yes—TTL-compatible trigger inputs and outputs are provided for master-slave timing with oscilloscopes, delay generators, or TCSPC modules.
What maintenance is required for long-term operation?
Dye cells are consumables with finite lifetimes (~10⁶ shots per cell under nominal conditions); no internal alignment or fluid handling is required during normal use.
