High Pulse Energy Green Laser
DM20/30/40-527 | DM50/60-527 | DM100-527
Features
- Patented highest pulse energy green laser
- Simplest, most efficient, compact monolithic laser head
- Diode lifetime of > 10,000 hours
- Optimized for pumping PIV and Ti:Sapphire amplifiers
- Pulse energy up to 100 mJ
- Proprietary twin pulse option
- Dual head option*
- Twin pulse option†
- Uniform beam profile
- Excellent pulse to pulse stability (~ 0.5% RMS)
*All models can be configured as Dual Head, please see DM Dual Head series
† PI’s patented twin pulse mode provides double pulses from a single trigger signal from the single laser head. Energy ratio of the twin pulses and pulse separation between the twin pulses is user programmable
