355 nm Series 3500 UV Lasers

Key Features

  • Up to 3W Power at 355 nm
  • Rugged, Low Maintenance Design
  • Excellent Beam Quality M² < 1.2
  • Q-Switched Repetition Rate
  • Stability Better Than 5% Over 8 Hours
  • Single Shot to > 100 kHz (Quasi-CW)
  • Low Cost of Ownership


The Series 3500 DPSS laser (US Patent #6,002,695) is the most efficient, high power, quasi-CW DPSS UV laser commercially available. Using only a single 2OW diode bar, the Series 3500 has demonstrated powers in excess of 3.0 Watts at 355 nm. This high efficiency conversion means that the laser can be operated at the normal specification, with minimum stress to the optical components and with a reduced diode current to extend the operating life.

Minimising the diode power required to generate the 355nm third harmonic output from the laser also minimises the thermal effects in the gain medium (Nd: YV04), which results in the lowest possible distortion to the beam. Both the second and third harmonics are generated intra-cavity, thus reducing the need for tight focusing into the non-linear crystals. The result is a stable, highpower UV laser with an M² specification of < 1.2, a near perfect TEMoo mode.
