Hello all,
I thought I will also ask from here for suggestions for suitable SLR lasers, as they seem rather hard to find and get.
Even though our station hasn't been operational for almost two decades (!), our HighQ 2kHz laser is degrading and spare parts are hard to get, hence we are looking for a replacement with somewhat similar specs (kHz, ~10ps, ~0.5mJ). The response from HiqhQ was that they are not providing any support or new suitable models.
So I've been asking around at ILRS meetings etc. and found out about Passat LTD, Ekspla, Innolas, Photonics, maybe Alphalas, I'm shure that there are other options as well, so does someone have some great suggestion which they would like to share?
I believe that our station is not the only one who are looking for a new laser.
All help is much appreciated!
Thanks,
Arttu, Metsähovi

Hi Arttu
Thanks for posting this. We are also thinking at Herstmonceux about our next laser and looking at the choices out there. Our HighQ 2kHz laser works, but is no longer supported.
Some options:
- Photonics Industries.
RGLX Series High Pulse Energy
Picosecond Lasers
It offers 4mJ in IR and 2.5mJ in green. It can fire up to 5kHz. However, the pulse width is 25ps.
https://www.photonix.com/product/rglx-series-lasers/
- Edgewave
PX-series InnoSlab Laser
It offers a maximum pulse energy up to 1.5mJ in IR and 0.6mJ in green. The pulse width is 10-12ps. It can fire up to 50MHz. The maximum output average power is 400W in IR and 200W in green.

https://www.amphos.de/products/amphos5000/
- Spark Lasers
Sirius
It offers a maximum pulse energy of 0.06mJ in IR and 0.032mJ in green. The pulse width is 10ps. It can fire at 1 MHz.
https://spark-lasers.com/produit/sirius/
- CNI
Mode-locked picosecond pulsed
laser at 532nm
It offers a maximum pulse energy of 2.0mJ in green. The pulse width is 15ps. It can fire at 5 kHz.

If you can decide what fire rates and pulse energies you want then the choices become easier. We would also be interested in IR operations.
