We make and sell lasers in a new kind of technology so that it is less expensive and good beam quality. All the divergence of diode lasers is less that 1.6mrad with a smaller spot size of less than 4.5mm. up to 5 Watt output power of red and bigger than 10 of Blue. Modulation is faster than 50KHz. You can contact me for details. Hope you will like it . Thx.
