NL300 series electrooptically Q-switched Nd:YAG lasers
NL300 series electro-optically Q-switched nanosecond Nd:YAG lasers provide up to 800 mJ per pulse at 1064 nm. The NL300 series nanosecond lasers are an excellent choice for many applications, including laser ablation and marking, OPO pumping and other critical tasks.

1) 20 Hz versions
2) Pulse energy of 20 Hz versions is available on request
3) Std. Dev., 8 hours after 5 second of warm-up time
4) At 1064 nm, FWHM
5) With respect to syncpulse, Std. Dev
6) "G"versions are ideal for OPO pumping. the lasers have underfilled laser rods, therefore their beam profiles are smoother if compared with "HT"versions.
7) Full angle at 1/e2
8) 550x530x590 mm for 20 Hz version of NL303G and NL303HT
