WebLasers operate on two general principles: light amplification using a gain medium (e.g. Ti:sapphire crystal) and feedback ensured by a cavity (e.g. two mirrors). As light is amplified in the excited gain medium, an intense laser beam is produced due to the feedback of the cavity, which is partially transmitting ( Figure 1 ). WebPower it up and see if the light glows. If it does then turn the potentiometer to check if the intensity of light changes. If it does, Everything is fine and you can proceed to the next step.
