Had to come back to just to say welcome back to you Pradipta. No apologies needed for being inactive. Everyone has their lives to contend with. It's nice to see your name active again. Kind regards.

Very good. Nice to see dye lasers on here again. Rarely discussed nowadays.

I think they are trying to get you to build the next generation Chucky

True but they are 20-150kHz so we wouldn’t perceive them as pulsed at all.

Nope. Not getting 3W at <400nm for anything affordable any time soon. I do have a cheaper alternative but still not cheap by any means. UV laser marking systems use a 355nm DPSS 3HG source...

There are many that don’t want the war. Agreed. But it’s not the administration that suffers brainwashing. I still remember tales from Russians in Ukraine at the time of the invasion starting. Them reporting home to their relatives and they not even believing their own flesh and blood. Not...

It’s also part of the propaganda narrative. We keep trying to pin a lot on Russia. Don’t get me wrong. I do not trust Russia either. But I also don’t trust the western governments right now. We can point out to Russians that they are being brainwashed and under constant propaganda as much as we...

Lol. And there’s me thinking it was the UK’s doing. Let’s be honest. It was probably a NATO move.

Good. Energy companies should not get away with profiting at the expense of their customers during a supposed crisis. Energy bills skyrocketed. The taxpayers here are now in debt and out of pocket at the same time from the energy price hikes. Just to have a mild winter and the energy companies...

Still on topic of price increases but did the US find that their energy companies were profiting of the supposed energy crisis?

There are many factors to the food price increases. I know the price of the cheapest tomato ketchup has shot up to around 4x the price it once was at the start of the pandemic. Pasta is now ridiculous. Milk has only just stabilised. It doesn’t matter what country you live in. There are...

I'm waiting for the general election to be announced in the UK too. Since Covid we've had no control at all of who we have in power. It's about time we get to dethrone a few numpties.

Why hasn’t this guy been banned already? If it was any one of us we would have been.

Why are you coming here and posting this pointless thread to test members on basic knowledge. This comes across as very arrogant imo.

>>>Warning<<< "If you think you need medical help or attention for an eye injury or any other medical problem, you probably do." "If you have been hit in the eye with a laser and feel you have suffered any type of eye injury as the result of an accident with a laser that may need medical...

Happy Easter Rich. Hope you have a great one!

Yep. What you did was a polycrystalline method. Now imagine the efficiency and effectiveness of a monocrystalline substrate. The benefits of being able to achieve this in electronics is too great for them not to keep pushing at them. It’s between these and graphene and I feel we are going to...

CVD yeilds diamond wafers. Just need the demand to increase and production costs to reduce.

I'm talking about diamond wafers like we already do with synthetic sapphire. We can then have monocrystalline diamond heatsinks
