Overview
The Ekspla Techno Q-switched diode-pumped solid-state (DPSS) Nd:YVO₄ laser is a high-performance ultraviolet (UV) source engineered for precision industrial and scientific applications requiring stable, high-brightness 355 nm radiation. Based on intracavity frequency tripling of the fundamental 1064 nm emission from a Nd:YVO₄ crystal, this system delivers nanosecond-duration pulses with exceptional temporal stability and spatial coherence. Its design leverages a master oscillator–power amplifier (MOPA) architecture combined with active Q-switching via acousto-optic modulation, enabling precise control over pulse timing, energy, and repetition rate. Unlike lamp-pumped or fiber-based alternatives, the Techno series maintains superior beam pointing stability (<5 µrad/°C), low amplitude noise (<0.5% RMS over 8 hours), and minimal thermal lensing—critical attributes for long-duration micromachining, ablation, and time-resolved spectroscopy workflows in controlled laboratory and production-floor environments.
Key Features
- Stable UV output at 355 nm with up to 3.5 W average power and pulse energies exceeding 35 µJ at 100 kHz
- Sub-15 ns pulse width (FWHM) optimized for high peak power (>2 MW) and minimal heat-affected zone (HAZ) in material processing
- Beam quality rated at M² < 1.3, supporting diffraction-limited focusing down to ~1 µm spot size with standard optics
- Integrated air-cooling system eliminating dependency on external chillers—reducing footprint and operational complexity
- Full digital control interface (RS-232, USB, and optional Ethernet) compatible with OEM integration into automated platforms
- Robust mechanical housing with vibration-damped optical mounts and hermetically sealed cavity for long-term alignment retention
Sample Compatibility & Compliance
The Techno laser demonstrates broad compatibility across non-metallic and composite substrates, including polyimide, FR-4, silicon carbide, fused silica, sapphire, alumina ceramics, and photoresists used in semiconductor packaging and MEMS fabrication. Its short-wavelength UV photons induce direct bond breaking in organic polymers and wide-bandgap dielectrics, enabling cold ablation with negligible thermal diffusion. The system conforms to IEC 60825-1:2014 as a Class 4 laser product, with integrated interlock circuits, key-controlled operation, and beam shutter functionality meeting EN 61496-1 safety requirements. It supports GLP-compliant operation when paired with traceable calibration logs and audit-ready software event logging (see Software & Data Management section).
Software & Data Management
Ekspla’s proprietary LaserControl Suite provides real-time monitoring and parametric adjustment of pulse energy, repetition rate, Q-switch delay, and internal temperature diagnostics. All operational parameters are timestamped and stored locally in CSV format with optional network synchronization. The software supports 21 CFR Part 11–compliant user access levels (administrator, operator, technician), electronic signatures, and immutable audit trails—including parameter change history, runtime statistics, and error logs. Integration with LabVIEW™, MATLAB®, and Python APIs enables seamless incorporation into custom process control architectures, while OPC UA support facilitates interoperability with factory-level SCADA and MES systems.

FAQ
What is the typical pulse-to-pulse energy stability?
RMS stability is ≤0.7% over 1 hour under constant ambient conditions (23 ± 1°C, no airflow disturbances).
Can the laser be synchronized with external equipment?
Yes—TTL-compatible trigger input and output ports support hardware-level synchronization with motion stages, cameras, and detectors at sub-microsecond jitter.
Is remote firmware update supported?
Firmware updates are performed via USB or Ethernet using signed binary packages verified by onboard cryptographic signature validation.
What maintenance intervals are recommended?
No routine optical alignment is required; periodic verification of output power and beam profile is advised every 6 months per ISO 17025-accredited calibration protocols.
Does the system meet FDA requirements for use in regulated manufacturing?
When operated within validated process parameters and documented in a qualified environment, the Techno laser complies with GMP Annex 11 and FDA guidance for computerized system validation (CSV).
