COMPACT AND LIGHTWEIGHT UV ns LASERS The Spectra-Physics Explorer® One™ series combines innovative and leading edge laser technology by uniting control electronics and laser resonator design into the same footprint of its predecessor, the Explorer®. Re-engineered to offer the most compact and powerful solution, the Explorer One It’s in the Box™ design sets the pace for innovation and unmatched laser performance in a tiny package. The Explorer One laser models are available in the UV at 349 nm and 355 nm. The Explorer One 349 nm is offered with pulse energies of 60 mJ and 120 mJ at 1 kHz, while the Explorer One 355 nm model produces over 300 mW of average power at a repetition rate of 50 kHz. The Explorer One Advantage • Unique all-in-one design – at least 8 times smaller than any competitive product • Lightweight – less than 1.5 kg makes this an ideal laser for use on a moving gantry • Feature rich software and hardware features for ease-of-use and simplified integration • Pulse energy stability of <3% for stable manufacturing processes • Superior flexibility from single shot to 200 kHz • Power adjustability 40 – 100% of maximum power • Single pulse energy measurement capability single shot – 200 kHz for precise and accurate laser performance feedback • Air-cooled design • Rugged, reliable design and construction for demanding 24/7 applications The Explorer One series’ ease-of-use and handling simplify integration into different tools or instruments. The very small dimensions of the air-cooled Explorer One makes this laser the technology of choice for system integrators who require integrating a UV laser into a tight space or small tabletop-like instrument. Only the 24 VDC supply cable and a serial or analog control cable is required to install and operate the laser on a moving system like gantry integration. Versatility and flexibility is realized by integrating advanced and value-added hardware and software elements such a first pulse suppression, active pulse detection, Burst mode, ondemand auto-calibration, and single pulse energy measurements up to 200 kHz. Explorer One’s output power is adjustable to optimize the laser performance to the application needs. Additionally, the system can be operated using TTL and analog control signals. Real-time pulse energy values are available on the integrated analog port. For applications that rely on the synchronization of multiple lasers, the Explorer One offers a dedicated port to operate multiple lasers synchronously or with precisely separated laser pulses. Based on the proven Explorer architecture, the Explorer One is extremely rugged, highly reliable, and ideal for demanding 24/7 applications. All optical components are soldered in place to ensure exceptional ruggedness and durability in harsh operating environments. No solder flux is used, thereby minimizing organic contaminants that can degrade laser performance. The Explorer One has been tested to endure shock and vibration with accelerations of up to 100 g. Like its predecessor, the Explorer One laser provides superior mode quality (M2 <1.2) over the full repetition range of up to 200 kHz. The Spectra-Physics patented intra-cavity design enables efficient conversion to the UV, resulting in the highest pulse-to-pulse stability for consistent processing and higher yields.
