High Pulse Energy (60 mJ)
Exceptional pulse energy for efficient pumping of Ti:Sapphire amplifiers, OPO/OPA systems, and dye lasers. Strong signal generation in LIBS and LIF.
Customizable Beam Profile
Output line-shaped or circular beams on demand — no external beam shaping optics required. Tailor the spatial profile to your specific experiment or process.
High Reliability, Long Lifetime
Robust diode-pumped solid-state design with conduction-cooled pump diodes. Proven long-term consistency in demanding laboratory and industrial environments.
Compact & Maintenance-Free
Integrated design with minimal footprint. No routine optics alignment or cleaning required — focus on your research, not your laser.

Typical configurations by application
Starting points based on common research and industrial requirements — every parameter remains adjustable.
| Application | Typical configuration | Why it works |
|---|---|---|
| LIBS | 1064 or 532 nm · 1–10 kHz · line beam · <2% RMS stability | High peak power ablates cleanly for strong, reproducible plasma emission; kHz rates accelerate multi-point mapping and signal averaging |
| LIDAR | 532 nm · high rep rate · <1 mrad divergence · ruggedized head | Narrow divergence extends achievable range; burst triggering synchronizes with fast scanners and gated detectors |
| PIV / LIF | 532 or 355 nm · kHz pulse pairs · flat-top sheet profile | Short pulses freeze particle motion; uniform sheet profiles deliver clean, unsaturated double-frame images |
| Pumping (OPO / OPA / Ti:Sapphire) | 532 nm · 60 mJ · M² < 1.3 | High energy with near-diffraction-limited focus maximizes conversion efficiency and tuning range |
| Precision machining | 355 nm UV · high peak power · industrial duty cycle | UV absorption and short pulses minimize the heat-affected zone in hard, brittle materials |

Frequently Asked Questions
Technical questions our engineers hear most often from researchers and system integrators.
What is a slab laser, and how does it differ from rod and fiber designs?
A slab laser amplifies in a thin, rectangular gain medium pumped through its large faces. The high surface-to-volume ratio removes heat efficiently, so it sustains high average power at near-diffraction-limited beam quality (M² < 1.3) — while keeping the high pulse energy and wavelength flexibility that fiber designs trade away. When an application needs beam quality and pulse energy together, the slab geometry is usually the right starting point.
Which applications is the CASEO-LASER-DHS series designed for?
High-repetition-rate, short-pulse work: LIBS elemental analysis, LIDAR and atmospheric sensing, PIV and LIF diagnostics, pumping of Ti:Sapphire, dye, OPO and OPA systems, and precision machining of hard, brittle materials. Standard wavelengths are 1064, 532 and 355 nm; alternative fundamentals and harmonic combinations are available on request.
Slab laser or fiber laser — how do I choose?
Choose a slab laser when beam quality, pulse energy, and wavelength flexibility dominate — spectroscopy, pumping, imaging, precision ablation. Choose a fiber laser when wall-plug efficiency, compactness, and maintenance-free industrial duty dominate — marking, welding, high-throughput cutting. The DHS series covers the first category with M² < 1.3, up to 60 mJ, and full harmonic coverage.
Can the laser be customized for my specific application?
Yes — every DHS system is built to order. Wavelength, pulse energy, repetition rate, pulse width, beam profile, spot size, polarization, control interfaces, mechanical envelope, and cooling integration are all configurable. See the customization section for the full option list and typical configurations by application.
What are the facility and integration requirements?
Single-phase 220 V ±10% supply (1 kW laser head, 1.4 kW chiller) and water cooling via the supplied chiller. Operating environment is 15–30 °C at 10–60% relative humidity, with a 15-minute warm-up from cold start. Head-only OEM configurations and remote-chiller options are available for system builders.
