Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Compared to most laser types, diode lasers are less expensive and more compact, making them ideal for small electronic devices, such as CD and DVD players, CD-ROMs, DVD-ROMs and other optical data storage devices. Laser printers, laser fax machines and supermarket bar code readers all use diode lasers. Diode lasers use much less power than most types of lasers. While gas and solid-state lasers require a power supply in kilo-volts, diode lasers typically run on small volt batteries.Hence , correct answer is option A .
