11. LPE afforded the technology of making heterojunction diode lasers . 12. Semiconductor diode lasers are typically used in plastic welding. 13. Unlike thermal lasers that cut tissue, Periowave utilizes a cold ( non-thermal ) diode laser . 14. The more powerful system, called a diode laser , will provide the equivalent of high-definition television. 15. Laser medicine : medicine and especially dentistry have found many new uses for diode lasers . 16. Diode lasers when used on soft tissue can cause extensive collateral thermal damage to surrounding tissue.17. In addition, the CD and DVD-player market has driven development of affordable diode lasers and optics. 18. Either designation distinguishes diode lasers from solid-state lasers. 19. In the same year, approximately 733 million diode lasers , valued at $ 3.20 billion, were sold. 20. It is also used to make diode lasers .
