Explorer One Compact and Lightweight UV NS Laser from Spectra-Physics

Spectra-Physics has introduced a new range of advanced UV laser technology - Explorer® One™ with compact and light weight design like its predecessor, the Explorer®. Combining laser resonator and control electronics in a single housing, Explorer One is available in two laser models: 349nm and 355nm. The Explorers One 349nm delivers pulse energy ranging from 60 to 120µJ at 1kHz, whereas the average power of the Explorer One 355nm is 300mW with a 50kHz repeatability.

Integrated with advanced software and hardware components such as active pulse detection, on-demand auto-calibration, and first pulse suppression, the Explorer® One™ allows convenient integration into different tools. Patented intra-cavity design of the laser model ensures efficient conversion of UV light, yielding increased pulse-to-pulse stability.

Key Features

The main features of the Explorer® One™ are:

  • Superior mode quality at up to 200kHz repetition range
  • Adjustable output power optimizes laser performance
  • Integration on a moving system through a 24VDC supply cable and a serial or analog control cable
  • Can be operated using analog and TTL control signals
  • Integrated analog port displays real-time pulse energy values
  • Unique port to synchronously operate multiple lasers
  • Robust, reliable design suitable for harsh operating environments
  • Does not contain solder flux, reduces organic contaminants
  • Resistant to vibration and shock with accelerations of up to 100g


The major applications of the Explorer® One™ include:

  • Thin film scribing
  • Metal marking
  • Wafer inspection and marking
  • Micromachining
  • General UV marking
  • Intra-glass and glass surface marking
  • UV titling
  • FPD repair
  • Laser microdissection
  • MALDI-TOF mass spectrometry
