Diode pumped q-switched UV laser from Advanced Optowave are available as Nd:YAG, Nd:YVO4 and Nd:YLF versions with wavelengths 355 nm and 351 nm respectively. For applications with higher pulse energy and lower repetition rates the choice is Nd:YAG and Nd:YLF , for cases at higher average power and higher frequencies Nd:YVO4 is better.

There are many different models available with power range 0.5 W up to 15 W, below 5 W they are air cooled. AOC lasers are well prepared for integration into a laser machining system. More than 1000 lasers have been supplied to the industry so far.

Wavelength

266nm, 351nm, 355nm, 527nm, 532nm
Average power:

>0.5W, >2W, >4W, >6W, >8W, >20W
Repetition rate

0-200kHz, 0-20kHz, 0-50kHz, 0-300kHz
Pulse duration

10ns, 15ns, 20ns, 25ns, 30ns, 40ns

Specifications

  • Variable repetition rates 0-300 kHz externally triggerable
  • A change in the repetition rate causes a change in the pulse duration and mean power; diagrams are provided for this
  • Each laser is optimized for a specific repetition rate
  • Beam attenuation can be adjusted via the duty cycle of the external trigger
  • There are models with air or water cooling depending on the performance
