Lee Laser introduces a pulse-pumped Nd:YAG laser with similar performance capabilities like the Serie 600 Pulse Nd:YAG Lasers , 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

Frequency tripling or third harmonic generation (THG) is a technique used to produce a wavelength that is one-third (1/3) of the fundamental wavelength of a laser.

For the 1064-nm fundamental of Nd:YAG, the third harmonic wavelength is 355 nm. 355 nm lies in the ultraviolet (UV) region of the electro-magnetic spectrum, and it offers many advantages over 1064 nm and 532 nm for laser processing, among which are :

• The shorter wavelength couples (or is absorbed) more efficiently with many target materials than does the 1064-nm fundamental wavelength, and for some materials even more efficiently than the second harmonic 532-nm wavelength
• The shorter wavelength has the potential to produce a beam focus spot which is 67 % smaller than that produced by the fundamental wavelength, and 33 % smaller than That produced by the second-harmonic wavelength
• Short wavelength lasers are valuable tools for scientific study
• Material removal is an ablation process rather than a thermal process

Applications:
• Machine tool
• Semiconductors
• Electronic
• Research
