Series LDPP Industrial Lasers

 
 Pulse-Diode-Pumped Nd:YAG Lasers

Since 1996, the lamp-pumped Series 600 Pulse Nd:YAG Lasers have become popular lasers for high-speed micromachining applications such as the manufacture of Stencil Masks for use in SMT, and medical Stent devices. Designed with the same industrial-grade ruggedness of our highly successful Series 800 CW (continuous-wave) and Q-switched Nd:YAG Lasers, the Series 600 brings Lee Laser performance reliability to heavier-duty applications of thin metal and gasket cutting and micro-drilling.

Now, Lee Laser introduces a pulse-pumped Nd:YAG laser with similar performance capabilities, but in a diode-pumped format. The new Model LDPP-50M offers the following performance capabilities:

  • Average power up to 50 Watts
  • Pulse energy up to 40 mJ (Watt-seconds)
  • Pulse width range 20 to 100 µs
  • Pulse rate up to 2000 pps
Diode pumping brings a new, higher level of performance to pulse-pumped Nd:YAG lasers. When compared with the highly regarded lamp-pumped Model 650M/CD laser, the Model LDPP-50M provides the following advantages:
  • Pulse build-up time of the LDPP-50M is only 20 µs compared with 70 µs for the Model 650M/CD.
  • Very fast diode current decay time. Much faster than lamp-pump current decay.
  • Very fast resulting pulse fall time. This will greatly reduce HAZ effects with the longer decay of the 650M/CD pulse.
  • Total extinction of the lase pulse occurs well before the extinction of the diode current pulse.
  • The beam quality is slightly better than the 650M/CD laser at comparable output power levels. Typical divergence for the 650M/CD is 3 mr at 19 Watts and 5 mr at 40 Watts.
The power station cabinet is 24 wide x 24 deep x 32.4 high, the same size as our Series LDP (CW) power station cabinet (ref. Drawing No. 130366).
