I can purchase an obis core series laser for 300 RMB (about 45 USD). Many wavelengths are available, such as 488, 532, 561, 552, and 505 nm. It uses OPSL technology, the same as the Osram PL530 or Sapphire lasers. Can it be used as a light source for holography? Also, does anyone have the driving method for it? I couldn't find its documentation. It has a 30-pin FPC interface.

Re: Can the obis core series lasers be used as a light source for holography?
Without knowing for sure I would guess these laser are well suited for holography. If it is something like this, https://www.coherent.com.au/products/la ... -1394.html, I would buy them all (particularly at that price!).whoiswei wrote: ↑Tue Aug 26, 2025 2:51 am I can purchase an obis core series laser for 300 RMB (about 45 USD).

Re: Can the obis core series lasers be used as a light source for holography?
Yes, this is the type, but it has no labels, only coherent packaging. The driver board is very expensive, and we can't find the pinout definitions. Perhaps we need to disassemble it to analyze the circuit. Here are some pictures provided by the seller.

Re: Can the obis core series lasers be used as a light source for holography?
I'm not sure about their origin. They appear to be brand new. Perhaps they were ordered directly from Coherent by an OEM manufacturer. I have no idea how they ended up on the market.I don't think Coherent will provide us with any support.Martin wrote: ↑Wed Aug 27, 2025 8:55 amWithout knowing for sure I would guess these laser are well suited for holography.

Re: Can the obis core series lasers be used as a light source for holography?
I bought one, it's small, but still a bit larger than the Osram PL530. However, I still haven't found any information on it. Perhaps I really need to open it up and do some analysis.Martin wrote: ↑Wed Aug 27, 2025 8:55 amWithout knowing for sure I would guess these laser are well suited for holography.
