A laser is a device that emits light (electromagnetic radiation) through a process of optical amplification based on the stimulated emission of photons. The term "laser" originated as an acronym for Light Amplification by Stimulated Emission of Radiation. The emitted laser light is notable for its high degree of spatial and temporal coherence, unattainable using other technologies.
Spatial coherence typically is expressed through the output being a narrow beam which is diffraction-limited, often a so-called "pencil beam." Laser beams can be focused to very tiny spots, achieving a very high irradiance. Or they can be launched into a beam of very low divergence in order to concentrate their power at a large distance.
Temporal (or longitudinal) coherence implies a polarized wave at a single frequency whose phase is correlated over a relatively large distance (the coherence length) along the beam. A beam produced by a thermal or other incoherent light source has an instantaneous amplitude and phase which vary randomly with respect to time and position, and thus a very short coherence length.
Plot
Nic and Jules are in a long term, committed, loving but by no means perfect relationship. Nic, a physician, needs to wield what she believes is control, whereas Jules, under that control, is less self-assured. During their relationship, Jules has floundered in her "nine to five" life, sometimes trying to start a business - always unsuccessfully - or being the stay at home mom. She is currently trying to start a landscape design business. They have two teen-aged children, Joni and Laser, Nic who is Joni's biological mother, and Jules who is Laser's biological mother. Although not exact replicas, each offspring does more closely resemble his/her biological mother in temperament. Joni and Laser are also half-siblings, having the same unknown sperm donor father. Shortly after Joni's eighteenth birthday and shortly before she plans to leave the house and head off to college, Laser, only fifteen and underage to do so, pleads with her to try and contact their sperm donor father. Somewhat reluctantly, she does. He is late thirty-something Paul, a co-op farmer and restaurateur. Despite his seemingly successful businesses, Paul has always shirked responsibility, most specifically in his personal life. After Joni and Laser meet with Paul, Nic and Jules learn what their children have done, and although they don't want Paul infiltrating their lives, they want to meet him especially as Joni and Laser seem to want to maintain some sort of relationship with him. As Paul's relationship with the entire family grows, which also includes him hiring Jules to design and construct his back yard, they have an effect on what he wants in life, and he in turn affects the family dynamic as well as each person's relationships outside of the family.

Nic and Jules had the perfect family, until they met the man who made it all possible.
Paul: Shut the front door!
Nic: Look, we have to be smart about this. You know, if we act like grubby bitches, we're just gonna make it worse.::Jules: I know.::Nic: Let's just kill him with kindness and put it to bed.::Jules: I'm with you, honey. We're gonna get through this, okay?::Nic: I love you, chicken.::Jules: I love you, too, pony.
[last lines]::Laser: I don't think you guys should break up.::Nic: No? Why's that?::Laser: I think you're too old.::Nic: [wryly] Thanks, Laser.::[Jules grins and puts a hand on Nic's knee, and Nic covers the hand with her own]
Jules: ...marriage is hard... Just two people slogging through the shit, year after year, getting older, changing. It's a fucking marathon, okay? So, sometimes, you know, you're together for so long, that you just... You stop seeing the other person. You just see weird projections of your own junk. Instead of talking to each other, you go off the rails and act grubby and make stupid choices... You know if I read more Russian novels, then...
Paul: Just making an observation.::Nic: Yeah? Well I need your observations like I need a dick in my ass!
Paul: It's hard enough to open your heart in this world. Don't make it harder.
Sasha: I'm just saying, the spermster's a hottie. Is he single?::Joni: Okay, first of all: Ew. And second, he's a really good person, so I prefer it if you didn't taint him with your "whore youth".::Sasha: Fair enough, hairy muff.
Jules: I wish you were gay, you'd be much more sensitive.
Paul: I'm just weird that way.
Laser: Why did you donate your sperm?::Paul: Because it seemed more fun than donating blood.

Cole Black: Hey metalmouth! Got another date with the trashcan.
Toe Thompson: That's it! Say hello to my little friend!
Toe Thompson: What's wrong with me?::Cole Black: What's wrong with you? Oh buddy where do I begin?
