Project idea

• Design and Development of compact Actively
  Q-switched minilaser based on
• Newly developed Yb doped laser crystals
  (YbKYW/KGW, YbYAG..)
• Compact and efficient intracavity Electrooptical
  Q-switch design
• High efficiency integrated electronics and user
  friendly interface

Why there is a need for a project?
5
The existing background for a project

• Diode pumped YbYAG passively Q-switched micro
  laser
• Resulted from FP6 NEXTGEN PCF
• Features
• Very high pulse repetition rate (up to 100kHz)
• Excellent beam quality
• High pulse energy (up to 100uJ)
• Small footprint
• Commercially available from Altechna
• Drawbacks which limits the field of applications
• Timing jitter (1-2us)
• Pulse to pulse energy stability (/-5)
• No ability to change easily the pulse
  duration/energy and thus pulse peak power

6
A plan of the project

• To utilize existing approach and background on
  DPSS passively Q-switched YbYAG microlaser.
• To employ initial results of actively Q-switched
  (by electrooptical modulator) Nd doped lasers.
• To employ Yb doped materials for this approach
  which has low quantum defect and thus high lasing
  efficiency, comparing with Nd doped materials
  used for present lasers.
• The approach is based on very compact and short
  laser cavity design comparing with the existing
  ones on the market.

7
The result of the project

• Actively Q-switched minilaser with following
  features
• Compact design
• Nanosecond pulse duration (lt2-3ns FWHM)
• Very small timing jitter (limited by electronics,
  less than several ns)
• High pulse energy stability (lt1rms)
• Efficient pulse triggering and sinchronization
  possibility
• Costs effective comparing with sources existing
  on the market

8
Typical applications and potential partners for
the project

• Material Processing (Marking, Cutting, etc.)
• Micromachining
• Seed for MOPA systems
• LIDAR Laser Ranging
• Laser-Induced Breakdown-Spectroscopy (LIBS)
• Biomedicine (e.g. flow cytology, DNA analysis,
  etc.)
• Many others!
• YOU are welcome to join us!
