Main categories of optical laser disks are CD-ROM,WORM Disk/CD-Record able(CD-R) Disks,CD Read/Write(CD-RW) Disk,Digital Video(or Versatile)Disk(DVD).
The three main parts of a laser are the gain medium, which amplifies the light signal, the optical cavity, which reflects and guides the light, and the energy source, which provides the energy to excite the gain medium.
As different people have different ideas on what is best you may be better off to go to the websites of each of the companies you listed andlooking for yourself. Internal optical disk drive are now essential these days as the Digital Versatile Disks or optical disks are the main way of installing programs, including operating systems, onto computers
In a ruby laser, spiking refers to the phenomenon where there are short but intense bursts of laser light emitted between the main laser pulses. This can happen due to the presence of residual optical feedback or internal reflections within the laser cavity, causing these uncontrolled spikes in laser output.
The main components of a laser are the gain medium, the pump source, and the optical resonator. Gain medium: It is a material that amplifies light through stimulated emission. Examples include crystals, gases, and semiconductors. Pump source: It provides energy to the gain medium to stimulate the emission of photons. This can be a flash lamp, diode laser, or another laser. Optical resonator: It consists of mirrors that reflect and amplify light within the gain medium. One mirror is fully reflective, while the other allows some light to pass through, creating the laser beam.

A Beam Detect Mirror is a special mirror that reflects a small portion of a laser beam for monitoring or detecting purposes without significantly affecting the main laser beam. It is commonly used in laser systems for alignment, power monitoring, or feedback control.
