  • Rugged, reliable design and construction for demanding 24/7 applications

The Spectra-Physics Explorer® One™ is the most compact series of UV and green diode pumped solid state (DPSS) q-switch lasers of its class. The It’s in the Box™ design incorporates features such as the very compact air cooled design, short pulse width, high peak power and a feature rich software into one single package and satisfy our customer needs with benefits such as ease-of-use and handling, high process quality and short time to market in cost sensitive tools.

The Explorer One laser models are available on three platforms. The standard platform provides up to 800 mW and 355 nm, 2 W at 532 nm. High Energy models are available exceeding pulse energies of 120 µJ at 349 nn, 80 µJ at 355 nm and 200 µJ at 532 nm. The extended Power platform the Explorer One XP is available with Power exceeding 2 W at 355 nm and 5 W at 532 nm. The High Power platform, the Explorer One HP is available with a Power exceeding 6 W at 355 nm.

The Explorer One Family consists of rugged and durable industrial laser designed for longevity and long-term stability in 24/7 applications. Exceptional performance including short pulse width for minimum heat affected zone, unmatched pulse-to-pulse stability and superior beam quality (M2 typically < 1.1) makes this laser the perfect tool for precision manufacturing. The lasers’ very compact "It’s in the Box" design offers a single package solution that allows fast and low cost integration for machine tool builders especially when space is a limiting factor. The very small dimensions of the All-in-One concept as well as low heat dissipation make this laser family the technology of choice for a small tabletop-like instrument. The combination of high output power and air cooled design reduces complexity, thereby resulting in short product development cycles and fast return of investment for our customers.

Versatility and flexibility are realized by integrating advanced and value-added hardware and software elements such as E-Pulse™ pulse energy control, burst mode, on-demand auto-calibration and single pulse energy measurements up to 500 kHz. The new E-Track™ dynamic pulse energy control feature actively measures and controls the laser for continual energy and power stabilization even under rapidly changing operating set points or environments. E-Track enables "on-the-fly" adjustments and fast gating for precision micromachining applications such as scribing marking, and drilling of tiny features.

In addition the Explorer One Laser’s output power is adjustable to optimize the laser performance to the application needs. The system can be operated using TTL and analog control signals. Real-time pulse energy values are available on the integrated analog port.
